Catchable fatal error: Object of class WP_Error could not be converted to string

[Neomr]

Hi there,

First kudos to you for this awesome theme. But I have an issue with event organiser and my theme. Below you'll find the error message:

Catchable fatal error: Object of class WP_Error could not be converted to string in /homepages/14/d13377013/htdocs/projekt/biz/klienten/axelfink/wp-content/themes/Minimalism-WordPress-Theme-master/administration/admin-functions.php on line 103

I've attached the admin-functions in a text document.

Thanks in advance for your help and support!

Marcus

Hi Neomr,

/homepages/14/d13377013/htdocs/projekt/biz/klienten/axelfink/wp-content/themes/Minimalism-WordPress-Theme-master/administration/admin-functions.php on line 103

Error message indicates the error is in your theme, on line 103.

Please use the support forums (or the plug-in repository support forums) for this though, as it doesn't appear to be a bug with Event Organiser.

If you're not the developer of the theme, then I'd recommending speaking to them too about this error.
