# [Plugin: Fluency Admin] Fatal error: Call to undefined function submit_button()…

 * The following error message is displayed where the “Submit” should be on the 
   options page:
 * > Fatal error: Call to undefined function submit_button() in /…/wp-content/plugins/
   > fluency-admin/wp-fluency-2.php on line 663
 * I had a look at the line and tried changing “false” to “true” but it didn’t make
   any difference (it’s now back at “false”). Any ideas?
 * Also, it seems the “Screenshots” tab when using the plugin installer doesn’t 
   load properly as screenshots aren’t showing up at all.
 * Thanks in advance,
 * LJ

 * Did you have any luck with this? I’m having the same exact problem.

 * This error occurred while we were using version 3.0.1 of wordpress, we’ve only
   just managed to “upgrade” to the latest version – 3.1.3 – due to the amount of
   hacking we had to do to the previous core files (we barely have time to work 
   on the site alone so backing up core files and noting down precisely what was
   changed and where took us a fair while), however, this issue seems to have been
   resolved by installing a more recent release of wordpress. If you’re using 3.1.3(
   or anything higher than 3.1) and still have this issue I’d keep on at the plugin
   developer for help.
 * On the other hand, try deactivating all plugins except from the Fluency admin
   plugin, then fire up its settings page again to see if the issue is still there.
   If it’s not then it’s being caused by one of your other plugins (I know this 
   from my own painful experiences with wordpress bugs). After this it’s a case 
   of trial and error, by activating each plugin until the issue re-occurs.
 * If you have a lot of plugins like us I recommend – rather than reactivating them
   one at a time – you do them in alphabetical order (for example, reactivate all
   plugins starting with **A**, then reload the fluency settings page, if it seems
   ok, move onto the **B**‘s, etc). Once the issue re-occurs deactivate all the 
   plugins of the last starting letter then reactivate _those_ plugins 1 by 1 until
   the issue re-occurs again, the last plugin activated is the cause of it. Then
   pass this info onto the plugin developer (and it may help to inform the developer
   of the conflicting as well)…
