Today I am using Osclass 4.4 and before the release of the new version of osclass 8.0.0 I had no problems on the site. Since the release of the new version of osclass, I got errors in the error_log file!

is it related?

@Vlad7
Thank you, it is actually error from osclass 4.1 or so.
Will be fixed in 8.0.1

I also found that mailing to users to subscribe to new ads stopped working because of this.

@Vlad7
I do not see any relation.
