Hello

I get the following error when try to open a product on front end
PHP Fatal error: Call to undefined function mb_convert_encoding() in /home/xxx/public_html/vqmod/vqcache/vq2-system_storage_modification_catalog_controller_product_product.php on line 545

I then disabled the opencart_vqmod.xml and everything works fine but none of the extension works.

I have not installed any extension that may have caused the issue.

Please help.

mb_convert_encoding() is a default PHP function. Either your PHP version is like SUPER old or this particular function is disabled (most likely). Contact your hosting provider on the matter.

So you have or not extension?
What oc version? Vqmod version?

Enable again and post code from line 545.

Read my reply. Extensions or VQMod don't matter, your error is quite obvious.

Please, stop confusing the guy with your replies. It has NOTHING to do with wrong code or some extension. See here. Function is just unavailable due to unknown reason.

That's it. You probably didn't have multibyte string functionality enabled.
