    order to work properly use Group Page instead of Page Also Make sure you type Side B ar with a capital B Why am I seeing PHP Warning Cannot modify header information headers already sent by messages at the top of my page If this is the first or only error message you re seeing it s usually an indication that there are blank lines spaces or other characters before the php or after the in a local customization files such as config php Double check the file and make sure there is nothing before the initial php It s often easiest and safest to eliminate any closing altogether On Windows it may be but shouldn t be necessary to use a hex editor to convert LFCR line endings to LF line endings in the local config php file When you save the file the encoding charset should be either cp1252 Windows1252 or UTF 8 without Byte Order Mark NotePad is an editor that can do this When you transfer the files tell your FTP manager to use text mode transfer or if that doesn t help binary mode transfer If the warning is appearing after some other warning or error message then resolve the other error and this warning may go away How do I make a PHP Warning about function session write close go away If you are seeing an error similar to this Warning session write close function session write close open some filesystem path to a directory sess failed No such file or directory 2 in your filesystem path to pmwiki php on line NNN PmWiki sometimes does session tracking using PHP s session handling functions For session tracking to work some information needs to be written in a directory on the server That directory needs to exist and be writable by the webserver software For this example the webserver software is configured to write sessions in this directory some filesystem path to a directory but the directory doesn t exist The solution is to do at least one of these Create the directory and make sure it s writable by the webserver software Provide a session save path value that points to a directory that is writable by the server e g in config php session save path home someuser tmp sessions unix type OS session save path C server tmp sessions Windows Why is PmWiki prompting me multiple times for a password I ve already entered This could happen like out of nowhere if your hosting provider upgrades to PHP version 5 3 and you run an older PmWiki release Recent PmWiki releases fix this problem Alternatively this may be an indication that the browser isn t accepting cookies or that PHP s session handling functions on the server aren t properly configured If the browser is accepting cookies then try setting EnableDiag 1 in local config php run PmWiki using action phpinfo and verify that sessions are enabled and that the session save

    php Simply add a line like the following EnableNotify 1 NotifyList notify alice example com group Main NotifyList notify bob example com name Main HomePage Controlling notification frequency To prevent flooding of recipients mailboxes the notify script uses a squelch value as the minimum amount of time that must elapse between messages sent to any given email address The default squelch setting is 10800 seconds three hours which means that once a recipient address is sent a notification message it will not receive another for at least three hours Any edits that occur during the squelch interval are queued for the next notification message The site administrator can change the default squelch interval via the NotifySquelch parameter enable notifications EnableNotify 1 NotifySquelch 86400 wait at least one day in seconds between notifications In addition individual addresses can specify a custom squelch parameter in the SiteAdmin NotifyList page Alice receives at most one email per day notify alice example com squelch 86400 Bob can get notifications hourly notify bob example com trail Profiles Bob squelch 3600 Charles uses the site default squelch notify charles example com Controlling notification delay Because a page will often receive several edits in rapid succession e g a long post followed by several minor edits a site administrator can also set a NotifyDelay value that specifies how long to wait after an initial post before sending notifications enable notifications EnableNotify 1 NotifySquelch 86400 wait at least one day between notifications NotifyDelay 300 wait five minutes after initial post Note that the squelch and delay values are minimums notifications are sent on the first execution of PmWiki after the delay period has expired For inactive sites this could be much longer than the specified delay periods This isn t really considered an issue since timely notifications are less important on relatively inactive sites However changes within the squelch time after the last notification will remain unnoticed if the wiki is not even visited for a long period after If this matters it might be necessary to make the server call pmwiki php regularly e g cron job Custom delay parameters cannot be specified for individual addresses in the SiteAdmin NotifyList page the delay parameter will be ignored notify edgar example com trail Profiles Edgar delay 600 Note for Windows installations Sites running PHP under Windows may not have PHP s mail function configured correctly Such sites may need to add a line like ini set SMTP smtp server com to config php where smtp server com is the name of your host s preferred outgoing mail server You may also need to set the sendmail from value if that is not configured ini set sendmail from noreply foo com Notify Variables EnableNotify Tells stdconfig php to enable the notify script EnableNotify 1 enable notify EnableNotify 0 disable notify NotifyFrom Return email address to be used in the sent email NotifyFrom wiki example com NotifyFrom Wiki server wiki example com NotifyDelay The length of time seconds to wait

    pmcrypt youradminpassword DefaultPasswords attr pmcrypt yourattrpassword Encrypting passwords in config php One drawback to using the pmcrypt function directly to set passwords in config php is that anyone able to view the file will see the unencrypted password For example if config php contains DefaultPasswords admin pmcrypt mysecret then the mysecret password is in plain text for others to see However a wiki administrator can obtain and use an encrypted form of the password directly by using action crypt on any PmWiki url on the target wiki or just jump to PasswordsAdmin action crypt on your own wiki This action presents a form that generates encrypted versions of passwords for use in the config php file For example when action crypt is given the password mysecret PmWiki will return a string like 1 hMMhCdfT mZSCh BJOidMRn4SOUUSi1 The string returned from action crypt can then be placed directly into config php as in DefaultPasswords admin 1 hMMhCdfT mZSCh BJOidMRn4SOUUSi1 Note that in the encrypted form the pmcrypt function and parentheses are removed since the password is already encrypted Also the encrypted password must be in single quotes In this example the password is still mysecret but somebody looking at config php won t be able to see that just from looking at the encrypted form action crypt may give you different encryptions for the same password this is normal and makes it harder for someone else to determine the original password Please note that the encrypted password should be created with action crypt on the wiki that will use it A password encrypted on one system may or may not be usable on another Removing passwords To remove a site password entirely such as the default locked password for uploads just set it to empty DefaultPasswords upload You can also use the special password nopass via action attr to have a non password protected page within a password protected group or a non password protected group with a site wide default password set Revoking or invalidating passwords If a password is compromised and the wiki administrator wants to quickly invalidate all uses of that password on a site a quick solution is the following in local config php ForbiddenPasswords array secret tanstaafl if in array POST authpw ForbiddenPasswords unset POST authpw This prevents secret and tanstaafl from ever being accepted as a valid authorization password regardless of what pages may be using it See Also The HandleAuth array which sets the required authentication level that is necessary to perform an action Cookbook RequireAuthor Protecting actions example Each action can be password protected Cookbook authors providing scripts with own actions can use this also but I ll limit the example to a by default not protected action source This action shows the wikisource of the actual page Sometimes you don t want that especially to Cookbook protect email or when using some conditional markup which should not be discovered easily or only by persons that are allowed to edit the page There
