For now,

You can login using this url: https://www.amijangla.com/wp-login.php

And then try disabling the plugins one by one to see which one is causing the problem

I’m unable to login thru https://www.amijangla.com/wp-login.php

along with the older warning messages.

In that case, try to FTP to your WordPress intallation directory (or use your cPanel’s File Manager), then navigate to /wp-content/plugins directory.

Now rename the suspected plugin by appending something like “_temp” to its name.

Ideally the suspected plugin should be the last one you’ve activated. Or it could be W3 Total Cache, as you said.

Now try loading your website. If everything works fine, you have found out the culprit.

If it still does not work, trying renaming ALL the plugins (a few at a time) and checking if the website loads fine.

Post the outcome here

Tried renaming all at oncw and also each at a time. It’s still the same warning message that appears.

Are you able to see the website at https://www.amijangla.com
or do you get the warning message there as well?

No I cant see the website. I see the warning there.

Its very difficult to pinpoint the problem without access to your setup.

Tell me one thing: have you accidentally/knowlingly edited any file from the WordPress setup?

Or any changes that you made just before the problem started appearing?

You have unexpected whitespace (either a space or an entire line) on line 1 of the /wp-includes/class-wp-rewrite.php file. See this guide for more info.

Alternatively, replacing the file with one from a fresh download may resolve the issue.

Does the file at /home/amijangla/public_html/wp-includes/class-wp-rewrite.php have a closing PHP tag ?> at the end? If it does try removing it.

the code for class-wp-rewrite.php is the same as the below link.

https://github.com/WordPress/WordPress/blob/master/wp-includes/class-wp-rewrite.php

I, unable to find the extra space int eh above code.

To my surprise this issue got solved automatically. Weird though. Thanks for helping me with this.

You’re welcome!
