Hello @iapial,
It appears the issue has been fixed. I had tried the last step mentioned and the website worked well.
Afterwards, I enabled all the plugins and updated this plugin. The plugin is now updated to the latest version (6.2.4) and no issues for the website so far.
I was wondering what happened in the morning. Maybe it might have happened due to updating multiple plugins at once.
Sorry for the inconvenience caused by me. But I got to know plugin support is excellent and communicating is happening in a timely manner. This will cement my trust on you guys. Thank you again for your time. Keep up the good work.
Best regards,
Bhanuka
