Hi there!
I've recently installed a payment module plugin. It seems to be working perfectly except for a little bug that really annoys me.
Just a second before being redirected to the tpv or payment page I get this message:
call_user_func_array() expects parameter 1 to be a valid callback, class'\GFP_Redsys´ does not have a method ´set_entry_meta´in /home/namarga/public_html/wp-includes/plugin.php on line 429.
So, apparently it's a usual problem with this plugin and the support guys in the company tell me to change the variable display_errors to false so the mistake is not shown.
First of all, I don't know where to find this particular variable within all the php files and second, I really don't know if this is the appropriate thing to do since, if there's an error, it would not be displayed hence, I would not be able to fix it if needed.
Could anyone advice me in that matter?
Thank you
Nora
