Likes System Problem Error

OK I started this thread in vBulletin >> Forum Error after upgrade

Now the problem is when I disable the likes system the error goes away.

Parse error: syntax error, unexpected T_STRING in */forum/includes/class_core.php(4425) : eval()'d code on line 211

This error is only in some threads not all of them can you please check.

EDIT: More investigations shows that if u like some members post then that thread start generating that error. As long as you dont like em the thread works fine.

Hello,

please try this:
Some threads do not open up when VBSEO is enabled
Article Content Dissapeared - language problem

After applying both of the solution it worked fine now.

Thank You
