Problem:

I am trying to install Toolset Blocks plugin, but get some PHP errors:

failed to open stream: No such file or directory

Solution:

Those PHP errors mean there are some broken/missing plugin files in your website.

Relevant Documentation:

Problem: Some automatic email notifications are not being received.

Solution: Sometimes when the site is inactive for extended periods, the internal cron is not triggered and notifications are skipped. Set up a true cron that pings the site periodically so that the internal WP cron is triggered at regular intervals to prevent this issue.
