   php on line _234_Warning: preg_match(): Unknown modifier ‘(‘ in C:\wamp64\www\
   nou\wp-includes\class-wp.php on line _235_And the are repeated many times. I 
   am using the latest version of WordPress and LearnPress. I tried to used past
   versions of both WordPress and LearnPress, but it did not work. I deactivated
   all plugins except LearnPress, and the issue still exist.Can you help me solve
   this problem?
