Have you tried removing the theme and re-installing it? IT’s quite possible that this is due to a corrupt installation of the theme.
It didn’t work… thanks anyway. Anybody else coming up with possible solutions?? Thank you very much
I’ve just downloaded, installed & activated that theme and it worked fie for me (with 1 wp_enqueue warning notice).
Well, I erased -as adviced-, re-installed, re-activated… and it does’nt work still. Same warning:
<html class=”
Fatal error: Call to undefined function mb_strtoupper() in D:\Inetpub\webs\mydomain\wp-content\themes\grey-opaque\includes\classes.php on line 227
Did you download a fresh copy of the theme?
What version of PHP are you running? The mb_strtoupper() function is a core PHP function available in PHP 4.3.0 and greater.
esmi, I guess so. I’ve downloaded the one available throught my desktop. You know, on “themes: install new theme”…
About my PHP version, Chip, I must confess I have no idea. I know, though, I’m running last version of WP.
Thank you guys for your help… I’m so new with this sh.. I mean, thing
As Chip said, mb_strtoupper() is a PHP function. It’s not being generated by WordPress so changing or updating WordPress won’t solve the problem, nor will modifying the theme. You should be able to check your PHP install by running <?php phpversion(); ?> or <?php phpinfo(); ?> – It really sounds like you’ve got a faulty php install so I would suggest asking this question in how to and troubleshooting.
Hi Chip,
Just a thought, have you tried contacting your hosting provider?
