[pmwiki-devel] Cannot Save Larger Pages

[Michael Elliott]

Hello,

I started having an issue where saving pages where the data size is larger than ~14.5 fail.  I have multiple PMwiki instances and it is happening on all of them.  Upgrading to the latest PMwiki version had no effect.  I also purge all page history and also tried recreating the page using a new name with no effect.

I have been working intensely with my hosting company and they say there should be no issue (below).
We checked the standard server-side request size limits. PHP is currently allowing POST requests up to 24 MB, and IIS request filtering is allowing up to approximately 28.6 MB. A 14 KB save is far below both of those limits, so this does not appear to be caused by the normal PHP POST size limit or IIS request-size limit. We are continuing to review this from the IIS/FastCGI side and will check for any related server-side errors or rules that may be triggering the 500 error during the PMWiki save request.


What can you recommend?


Thank you,

Michael Elliott
