First of all, absolutely great plugin! As i mentioned in my review, it's a "life saver"! Thank you for your effort!
I recently tried to upgrade from 22.214.171.124 to 2.0, and everything looked good, even the migration, until i clicked on 'Metaboxes and widgets'. At the first look, nothing happened, the list was not populated after a refresh. There was no data even before i hit refresh in the list. Then, i tried to debug, as much as i could, what went wrong.
I have the error below every time i try to refresh metaboxes and widgets:
WordPress database error MySQL server has gone away for query SELECT option_value FROM wp_options WHERE option_name = 'aam_metabox_cache' LIMIT 1 made by do_action('wp_ajax_aam'), call_user_func_array, aam->ajax, aam_View_Ajax->run, aam_View_Ajax->loadMetaboxes, aam_View_Metabox->retrieveList, aam_View_Metabox->buildMetaboxList, aam_Core_API::getBlogOption, get_option
Then i tried to find 'aam_metabox_cache' in my db, but there is no field or property or description or anything by this name. Then i tried to run the query "SELECT option_value FROM wp_options WHERE option_name = 'aam_metabox_cache' LIMIT 1" manually in phmyadmin, but the query returned NULL. And that's it, i don't know what else to do.
Before the upgrade i had the list of metaboxes and widgets populated, but after the upgrade it vanished, and the refresh is generating the error above.
What else can i try or do?
