I’ve Asked to Fastcomet support team, and they told me that the problem could be of the theme…so..what can i do? can you investigate? because its very strange.
“Hello,
Thank you for contacting our Technical Support Team.
I was able to recreate the “flashing” issue you are experiencing on your “distefanobiancheriaperlacasa.com” website, but please note that since there is not any errors, we are not able to track the cause of the issue. However, I assume that the issue is coming from your website’s theme. Thus, I would suggest you to simply change the theme of your website in order to resolve the issue.
If you need any further assistance, feel free to contact us.”
