We are running a fairly large multisite installation that uses Admin Menu Editor Pro. This morning our dev site stopped working and it looks like the reason was that we have over 17,000 entries in our
wp_sitemeta table from
ws_menu_editor_pro. Our php errors log also showed SQL errors from menu editor pro. Deleting those 17,000 entries brought the dev site back online. Fortunately it doesn't seem to be an issue in production.
Has anything like this been raised before? Any ideas what's the cause of the error? Any planned updates to fix it? Any helpful tips meanwhile?
