Pligg version: 2.0.2
PHP version: 5.5
MySQL version: 5.5.36-ccl-lve

Every single action will trigger a pair of this message in the error log:

PHP Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in {my website address}/class.compiler.php on line 246

I deleted 412 of these on a single day. Is this something that should be corrected or ignored altogether?
i didn't see any similar posts on this topic. i'm having an intermittent issue (90% of the time), when sending a private message to new users, the result is a 404 page. the problem ONLY happens on accounts created by real users, not test users. having problems getting it to repro since i don't want to send a load of test messages to my new site users.

running OTnews by OxyThemes on Pligg 2.0.2.
Any gurus out there who might know why my error log is reporting this warning?
