For 406 error, when doing a new page creation, when I hit the SAVE, I get:
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.
I cleaned all caches manually, and compared two releases of the same version where one is working and one is not. Here are the diffs I found (which I fixed) but it did not help:
- wiki/img/icons/ed_image.gif missing on bad site (so restored)
- wiki/img/icons/insert_table.gif missing on bad site (so restored)
- wiki/db/virtuals.inc empty and existing on bad site (so removed)
- theme/base_files/favicon directory and content missing on bad site (so restored)
- whelp/ is empty folder found on bad site (so deleted)
