So, I eagerly installed the latest and greatest, and am presented with these errors at the top of every single page.
Warning: Invalid argument supplied for foreach() in /.../wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Autoloader.helper.php on line 183
Warning: Invalid argument supplied for foreach() in /.../wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Autoloader.helper.php on line 183
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /.../wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Autoloader.helper.php:183) in /.../wp-content/plugins/event-espresso-core-reg/core/EE_Session.core.php on line 366
WordPress Version: 4.1
PHP Version: 5.5.18
MySQL Version: 5.1.55
So, I did the usual troubleshooting – reverted to 2015 theme, turned off all other plugins and still got the errors. Then, I created an entirely new database and, with no other plugins activated, no pages set up, no settings changed, etc – literally just the basic initial WP data – I am still seeing these errors!

Hi Peter,
The errors seem to indicate that your Event Espresso plugin directory and its files are non-readable. Can you check your server’s file permissions for the wp-content/plugins directory?

Hi Peter,
A couple things you can check/verify:
1) When you uploaded 4.6, did you first delete the older version of Event Espresso 4? If not, you can try re-installing, but first delete the Event Espresso plugin’s folder, then FTP up the new files.
2) You can add some debug code right after line 182 in /core/helpers/EEH_Autoloader.helper.php to get a better clue on why it’s throwing this error.
So line 182 is $filepaths = glob( $folder. '*');
Right after 182 you add this:
if ( empty( $filepaths ) ) {
var_dump($folder);
}

Yes, I deleted the old plugin’s folder first. Also, as part of troubleshooting, I have deleted the old API folder and the ticketing add-on folder too. Actually, I deleted the entire event espresso folder in Uploads.
For the first “Warning: Invalid argument supplied for foreach()”:
string(161) "/.../wp-content/plugins/event-espresso-core-reg/modules/single_page_checkout/css/single_page_checkout.css/"
For the second:
string(159) "/.../wp-content/plugins/event-espresso-core-reg/modules/single_page_checkout/js/single_page_checkout.js/"
The folders are all 755 and the files are 644, btw.
Oh, and there’s now a 4th error (before I added the debug code):
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /.../wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Autoloader.helper.php:183) in /.../wp-content/plugins/event-espresso-core-reg/core/EE_Session.core.php on line 366
Thanks

Can you try switching to a fresh database, go through the installer, and see if it is still erroring?

Yes, I had already tried that before my initial post.

Hi Peter,
There’s a fix we included in one of the releases today that should take care of the Invalid argument supplied for foreach() warning you’re seeing.
