Hi.
This is a problem that apparently affects your XStore Core plugin. Everything was working fine in our WordPress until we updated to the latest version of Elementor (which also applied an update to the DB).
Then a critical error occurred that broke the website. We have seen that this version of Elementor works without problems together with other plugins, but if you keep the XStore Core activated then the error occurs.
Is it possible that there is an incompatibility between both plugins in the current version? It doesn’t seem to be a bug in the Elementor plugin update as it works fine (as long as XStore Core is deactivated, but this plugin is essential for your theme to work).
Suggestions welcome, thanks!
