Bad server response during edit

[tzmudzinski]

I have an error: Bad server response after click save in every section.
I had 2.6 version and there was everything ok after upgrading to 2.7 (and 2.7.2) the problem starts occur
I have the following lines in error_log:
[01-Dec-2014 12:26:10 UTC] PHP Fatal error: Cannot unset string offsets in
/home/application/Espo/Services/Record.php on line 326

After downgrading to 2.6 i have the same problem.
Reinstal doesn't fix the problem

I'm experiencing a similar issue with 3.4.2, I have a bad server response error every time is sign in, or try and save an entity, it even prevents me from creating(leads, but not the other entities)...

here's what the log is saying, the object m_opportunity was deleted but for some reason it's still saying a link exists
