Can't export database

When i try export the database, i receive that error:

What does that translate to please? You can force the CMS in to English if that’s easier from the CMS settings.

I suspect it’s a generic application error message, in which case, it looks like you may be on shared hosting of some kind? If so, they normally lock down PHP’s ability to run shell commands as is needed to create a database backup.

You’ll need to use a tool such as MyPHPAdmin or similar to do the job instead.

There was an error in the application
Execution is not available.

I believe that the hosting is shared.
How do I properly backup using phpMyAdmin?

You’d need to ask your hosting provider for instructions on taking backups of the databases you’re hosting with them
