We found that Elementor Pro also displays the message that the Elementor plugin is not activated even if it’s activated https://gyazo.com/e94897ff1462e210e9c4ee34b9676c9e And it happens even with the default theme which means that XStore theme is not the reason of the issue.
Also, as I can see that if I change the permalinks type from Post name to Plain both errors disappear. So, something is wrong with the server settings or with the .htaccess rules. Contact hosting provider to get help with this issue. We can’t fix that from theme side because our theme is not the reason of the problem.
