Hello,
Yes, because XStore core has a lot of options and uses large body response.
Please, follow my instructions and contact your hosting provider to ask to increase the Response body limit because you have “ModSecurity: Output filter: Response body too large (over limit of 1048576, total not specified)” error.
We can’t increase the limit from the theme side. You need to contact your hosting provider to do this, do you understand?
Regards
