Hello Ilya,

Thank you for purchasing Amelia, and for reaching out to us.

This usually happens when your database is configured to use SQL_BIG_SELECTS, but Amelia has that turned off by default because the majority of databases don't use it.

If you know your way around the database, you can enable this yourself by going into the wp_options database table (wp_ is the default database prefix, but it could be anything on your end):

In there, click on SEARCH at the top, and in the "option_name" column search for "amelia_settings":

The search will return only one row, and you need to edit it:

In "option_value" column, search for "pdoBigSelect":

It is currently set to false, as you can see in the screenshot above, so just change that to true, save the settings, and try editing the event again.

If that fails, or if you're not familiar with phpMyAdmin, please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

Hello Ilya,

We are glad that we're able to help you. If you have any more questions please feel to open another ticket.
