I removed All files from File Manager
Exported WP Post & WP Terms Related SQLs
Removed Everything Related to the Website
Created New site ( same domain )
Installed WordPress as Normal
Removed Default SQLs ( WP Posts & WP Terms )
Kept WP Options and Others
Imported WP Posts & WP Terms to this New Database.
The site is NOW Working.
NB: I don’t know why and how this issue came after the Update…
Default theme page size 270KB
GP Size 29KB
Thanks for this Great Great Theme.
