Hi,
I’ve recently encountered an issue, preventing use of the editor.
Some examples of errors from the log:

PHP Warning:  Invalid argument supplied for foreach() in /home/educationforneed/public_html/wp-content/plugins/wp-accordions-pro/themes/tp-accordions-pro-themes.php on line 136

PHP Notice:  unserialize(): Error at offset 0 of 44225 bytes in /home/educationforneed/public_html/wp-content/plugins/wp-accordions-pro/wp-accordions-pro.php on line 94

 
Thanks
