I wrote in another post, but it was marked as "resolved" before I wrote in it and didn't want to risk not having it looked at. Please ignore the other one.
Anyhow- I had the CircloSquero theme installed on Wordpress, and then went ahead and installed Avisio and activated it. I edited the widgets.php of this theme, it didn't work, so I put the original file now. But after doing this, when I go to the website (wearemakingadifference.org) only a FATAL ERROR appears. It won’t let me access the wp-admin either.
The error reads: Fatal error: Class ‘WP_Widget’ not found in /home2/wearemak/public_html/wp-content/plugins/breadcrumb-navxt/breadcrumb_navxt_widget.php on line 19
This is a file found in the Circlosquero theme. Do you have any idea how to fix this? There’s no backup of this site, so any help would be tremendously appreciated. I don’t know if to delete that breadcrumb-navxt or the entire Circlosquero theme? Or if either of those will even help, I just don’t want to play around with it and risk messing it up more.
