I recently had to do some plugin updates but in doing so I get a critical error message and the site shuts down. I’ve had to alter the ‘plugins’ folder in the cPanel File Manager in order to get rid of the critical error message but would have to reactivate each plugin. I’m pretty sure the problem has something to do with the Xstore Core plugin.
And because of that issue, I’m assuming that’s why the CSS won’t load properly?
You are using XStore version 5.2. The latest version of XStore is 6.2.10. It could be the reason of your problem. Very likely you updated XStore core plugin to latest version but did not update theme. Provide us wit FTP access to your site to update theme and plugin and check if it helps.
