I am trying to create content templates by duplicating existing ones, but the usage checkbox on the sidebar doesn't show up. So I can't allocate the template to the right form.
+ it is constantly says that it has an error establishing the database connection.
I have looked into it now and the only cause on why it is happening that I found, is the processes being reached from time to time:
Most likely, these spikes are caused by your plugin processes, so in this case, you would need to try and optimize the plugins and check for any cron jobs set up by the plugins that you do not require.
If you are unable to cut down on the processes and are still experiencing issues with the database, I would suggest upgrading your plan to a bigger one, so you would have higher limits for these resources 🙌
