Hi,
I am noticing a lot of error in the console, is it from the theme or the server is causing it due some permission issue.

Hello shariful18,
Most likely, these type of errors comes from your untested plugins. Try to disable all of them leave just only the required plugins which come bundled with the theme core files and rule out any conflicting plugins. Clear all the caches and check the results.
If the problem is still there, you should provide your website URL so I can take a closer look at it.
Thanks for your understanding!
Hi,
Currently I have very few plugins installed. They are very essential as well. I am guessing it is not from the plugins.

Kindly have a look at it on the following URL:

I really appreciate your prompt response!
Thanks
Hello shariful18,
Please notice that the first step in WordPress debugging is to deactivate all of the untested plugins. I have checked your list above and I saw that you have some untested plugins, sorry! Please remove all of these, revert the theme to the default state, clear all of the caches and check the results. These plugins might interact with the theme and cause some errors.
Please keep in mind that error does not appear on a fresh install.
Thanks for your understanding!
Hi Catalin,
I will need to update the WordPress, that must be causing the issue. Thanks for pointing it out.
