Two PHP products installed on a basic Centos LAMP stack running DirectAdmin:
- Media Wiki
Issue In Media Wiki, I edit an existing page but cannot preview or save it. I get "page cannot be found". In recent log entries I see 501.shtml. This does not happen on all pages, in fact on very few.
I just looked on a Drupal site where I know I have seen this, I spot checked 20+ pages and found it on one. It is a page that has code (in code tags). I took the page that exists, that just cannot be edited and copied the body to a new node, and it will not let me save it. Then I took the body contents and tried to create a new node on another Drupal website, It will not let me save it. So there is some content in there, Drupal and evidently mediawiki do not like. All the code is in tags.
This is what is causing it to not save:
Added to template.php just above tertiary content
Anyone have any thoughts on what could be causing these pages to fail for two unrelated pieces of software?
