My wordpress(5.3.2) site is hosted in a cPanel shared hosting server,it has stopped running & now i'm getting HTTP ERROR 500, i've tried changing to default twentytwenty theme, disabling all plugins, and even falling back to wordpress basic .htaccess config, nothing works.
I'm not using any sub domain or multisites wordpress installation for this site, & my hosting is responding fine except for this wordpress site i've mentioned.
does anybody have any idea what might be the issue here? i'm pretty confused now .
