my page with ClassiPress not shows ADs
Hi I have a serious problem, the change yesterday in my hosting server, back up and move accounts through cPanel. The problem is that my page ClassiPress shows no ADs issued and categories to be selected are the following message:
Fatal error: Call to undefined function mb_strlen () in / home / cambalac / public_html / wp
-content / themes / ClassiPress / loop-ad.php on line 25
Also I tried to upload other older backups of my accounts, but nothing happened. Could be due to changing IPs from my reseller account??
My page ClassiPress is this: cambalache sevilla | anuncios gratis | cambalache | compra venta | anuncios gratis en internet
