Issues with saving page having comments enabled

[casdero]

Hi guys,

I have a little issue I debugged as far as I could for the moment.

I have a simple page (title, a checkbox, a textarea and the comments field) working as a guestbook page. Initially there were no problems with creating the page and setting the content of title and the textarea field. Currently some comments have been made on the page.

Now I want to change the content of the textarea field, but sadly nothing is happening in the administration area. The green bar saying "successful saved" (or something like that) does not appear.

I checked the mysql log file, and also reassured my of the normal behavior on a different page without comments, how the log must be look like. So I found, that really nothing is happening. No insert statement.

I don't think this is the expected behaviour, but I'm not sure how to fix this issue or debug this some more. Hope you can help me out here.

My environment installation looks like the following:

ProcessWire Core (Stable/Master) 2.5.3

JqueryDataTables 1.9.4

ModulesManager 2.1.6

ProcessDatabaseBackups 0.0.3

ProcessLatestComments 0.0.3
