You were “working on it”? Doing what? Can you elaborate?
Can you open a console or otherwise access the backend of your site? SSH/FTP, etc.
If you can do that, you’ll want to rename the buddypress folder inside of /data01/ramonbenton/public_html/wp-content/plugins/. Then, you should be able to get into your website, at which point you need to look at the file bp-activity-filters.php on line 232 to see why it’s calling the function bp_activity_do_mentions(), what that function does (if possible), and maybe talk to the makers of the buddypress plugin and see what the problem is.
Of course, this all depends on why the problem is happening in the first place.
Something to check out here:
https://phpxref.ftwr.co.uk/buddypress/src/bp-activity/bp-activity-filters.php.source.html#l232
This website points to the function being at /bp-activity/bp-activity-functions.php on line 26. You might want to check to see if the file’s still there, what the file’s permissions are, etc.
