Getting an error that looks like i am missing some plugin.
“Fatal error: Call to undefined function is_plugin_active() in” Also the submit changes button is missing on that page. See screenshot.
Odd. It is a standard WordPress core function and is simply checking for WP plugins such as BuddyPress and Mingle… And as expected- works fine here and, as far as we know, for everyone else at the moment.
I can’t believe there would be anything odd or different about your WP Admin environment. Will need to do some research alongside @mr papa
Yea crazy stuff going on.. 
Found this in me error log: [23-Aug-2015 16:47:21 UTC] PHP Fatal error: Call to undefined function is_plugin_active() in /home/ebaymoto/public_html/blog/wp-content/plugins/simple-press/admin/panel-profiles/forms/spa-profiles-options-form.php on line 71
I’m trying to make the forum more user friendly. Disabled CloudFlare rocketloader on the forum page and wp-admin. I was thinking RocketLoader was causing that error but no luck.
Thanks as always for your help!
yeah, not sure under what conditions a standard wp function wouldnt be available… and cant seem to replicate it on multiple sites…
do you know what option you have selected for display profile mode?
I do not have that setting, Is it supposed to be where the error is generated?
you do have it… see the tab with profile display mode – yes, you have the error instead… which is why I want to know what you have for that option and why I gave you a screenshot… from the available choices in my screenshot, it should be pretty easy to know what your option is… trying to figure out if its option dependent…
We are talking about Profile > Profile Options right? If so part of that page is cut off and there is no change settings button.
If i uncheck the option > display profile tab on login, there is no save changes button to commit the change.
No… look at my screenshot… there is profile display mode option… display profile information in… you dont see it cause you have the error… but I want to know what your option is…
how do you display profiles???? you must know that… are they in popups? full page? buddypress, mingle, or other???
okay… still cannot generate that error with that option either..
this is wp 4.3, right?.
going to have to think on it more… and maybe @yellow-swordfish will have some ideas…
Makes no sense to me at all. I guess we could ‘include’ the file to make sure but I see no reason whatsoever why we should need to…
