Hello shane,
thanks for sharing your solution.
Unfortunatly it did not solve our problem.
For Ubuntu 20.04, there is no php7.0-sqlite3. php7.4-sqlite3 is already installed.
I enabled the extension in php.ini, but still get the same error.
As our partner could not solve the problem, i really HOPE it will disappear as soon as we upgrade to 2.0, what is planned for 2nd half of the year.
