[pmwiki-users] Can't edit pages after upgrade

[Petko Yotov]

You already did reasonable diagnostics, this will help. What were your 
previous PmWiki version and PHP version?

Sometimes, if after the upgrade there are older PHP files that somehow 
were not updated, you can see weird things like this. So check the times 
and sizes of pmwiki.php and the files in pmwiki/scripts.

When upgrading check the page Upgrades to see if there are any changes 
that may potentially affect your wiki, if so we document what variables 
can be set to restore a previous default behavior.

Also see if there are recipes and skins that have more recent versions 
and can be upgraded. For example in the past, calling the 
htmlspecialchars() function on text with international characters or 
typographical punctuation could cause blank pages or sections (we added 
the PHSC helper function to prevent this).

After all that, if you still have troubles, check the page 
Troubleshooting with generic steps to search for what could be the 
reason - disabling all customizations, recipes, skins, then enable them 
one after another to see what breaks it:
   https://www.pmwiki.org/Troubleshooting

If we can identify a problem with the core, I'd be very interested to 
work to fix it ASAP.
