Fatal error: Call to undefined function mb_strlen()
Hi,
I just moved my website to a new VPS server. I used the 'Restore a Full Backup/cpmove file' in WHM but I got this error in my front page:
Fatal error: Call to undefined function mb_strlen() in /home/mywebsite/public_html/
wp-content/themes/classipress_child/loop-ad.php on line 25
The rest of the site is working fine, except for the index as mentioned.
Thanks for your help.
