Probable Ivalid Request - CSRF Token?

[wade421]

Hi, Every time I'm trying to log in at the front end admin panel or create a new user it shows "Probable Ivalid Request"
Back end login works fine.
I've tried to disconnect all java scripts and plugins that may conflict with osclass but nothing worked. 
OSCLASS 3.5.3
Please help!

Provide a link of your site, if you want/can.

And enable Osclass debug mode log. Any errors in there ?

Debug log is clear.

Subject website is officetracer.com executive suites and turn-key offices listing service in the U.S.

Thank You

Ok, then switch to the default Osclass theme for a while (bender) and see if the problem is solved.

This theme is what ? Says bender but it is not. heavily customized.

It's heavily modified bender, but it was working like this before. I have another heavily modified bender connected to the same db and it works ok. How shut down the CSRF?

Just installed another theme - same error. I wish I can restore it from a back up, but don't know when problem occurred first, since was always using an back end admin. The last time front end was checked was in March 2015
