Problem with saving a menu

[birdy10]

Hello Slim & dapper,

Great plugin, but we have a we have tiny issue on the Bezuidenhout website;

When I try to save a standard WordPress menu it will process for a minute or so then show
a 500 error. When I disable the Theatre plugin the menu is saved instantly. Enabling again gives the error as before.

• So I did what the error message suggested, but permissions in root & folders are ok
• raised/lowered WP_MEMORY_LIMIT, no effect
• I deactivated other plugins, no effect
• This is the error message, but when googling I can't find any clue what to do with this:
  [Fri May 03 13:43:42.478073 2019] [:notice] [pid 46702] [client 185.165.70.166:36532] mod_hive matched URI http://bezuidenhout.nl/wp-login.php (/home/bezuiden/public_html/wp-login.php) with match 2, referer: https://bezuidenhout.nl/wp-login.php?redirect_to=https%3A%2F%2Fbezuidenhout.nl%2Fwp-admin%2Fnav-menus.php&reauth=1

So, can you please help me out here?
thank you,
Harold Vogelaar

Can you try this:

1. Create a backup of the database.
2. Open the tabel inside phpMyAdmin.
3. Run the following query:

   DELETE FROM `wp_options` WHERE `option_name` = 'theater_transient_keys'

4. Edit a menu and save it.
