"a critical error has occurred" in wp-admin

[gastornov]

Expected Behavior

Current Behavior

When the pro version is activated from wp-admin, the basic version is deactivated automatically.
But - when plugins are activated ”in bulk”, both plugins get activated, causing wp-admin to be blocked by "a critical error has occurred"

Possible Solution

Steps to Reproduce

1. rename plugin folder to "plugins_old" via ftp
2. create folder "plugins" via ftp
3. delete or rename folder "plugins"
4. rename folder "plugins_old" to "plugins"
5. go to wp-admin > addons, tick all plugins, choose "activate all"
6. wait for error message

Hi @gastornov

thank you for reporting this issue!

We'll take a look and try to fix this issue for the next plugin update.

Have a nice day!

Hi @gastornov,

could you please let me know which mailer you were using when you bulk activated both Lite and Pro versions of the plugin? Did you by any chance use one of the Pro mailers?

We've tried to reproduce this issue, but could not.

I think the actual critical error in your case was caused by a bug in our plugin, where if you used a PRO-only mailer (configured in the Pro plugin) and then activated the Lite plugin version it would throw a PHP fatal error. This bug will be fixed in the next major plugin update.

As for the bulk plugin activation - it does not cause any issues on its own as far as we tested it.

Thank you again for reporting this issue and have a nice day!

Hi, sorry for the late response; yes, I use Office 365 mailer.
