I was using my OJS for 2 years, and everything was just fine, after I updated my PHP on my server, then all pages gone to "Deprecated errors", I searched the forums, I found that I should turn of PHP Deprecated errors and it's because of PHP 4 blablah..., I did it, now all errors are gone and index is looking good, but "Sidebar" also is gone!!! there is no sidebar in home and other pages, it's like gone gone!
What has happened? How I could resolve this issue?
Please kindly let me know.
