I momentarily disabled Page Preloader and started noticing this line repeated a bunch of times on the frontage (can be seen just below the slider):
Warning: A non-numeric value encountered in /var/www/zafariqbal.dk/public_html/_zafariqbal_V2/wp-content/themes/rife/advance/utilities/cpt-album.php on line 250http://v2.zafariqbal.dk/
Edit: Removed an issue, which I can't reproduce or revert to at all anymore. While trying, I noticed something new and it happens in both Firefox and Chrome:
I have created a page (duplicated actually, using a plugin) as my frontpage. When reverting edits, it jumps to an album in the backend.
I tried reproducing it using a new page and a different duplicated page as well, but can't reproduce the behavior with those - but it keeps happening with my frontpage.
