Hi , thank you for helping me . Yes I have just solved the issue by going to Asset Optimization > Configuration and uncheck the CSS and JavaScript files . I didn’t check if one or both of them cause the problem but I’m happy with the results .
can i ask about another thing or should i make another fourm. gtmetrix tells me that just the background video on my website does not have CACHE TTL , did i miss anything for video caching in the plugin ?
