The error has been solved by hosting company.

The error is a block from hosting company’s mod security. They have whitelisted it and now everything works fine.

Thanks Luke for your help too!

I have created a new post and added only one button with a different color than that are available in button colors.

The error happens only when I choose a different color for button than few available colors.

The error shows like this: https://prntscr.com/puikn9

Again I have checked on buttons,

If I clear the color of button (that will make my button from orange to black background) then everything works fine (i can preview and update blog posts).

Also if i create a new blog post and add only a single button with orange color(#f23c00) then it shows that error.

How a button color can cause error?

I have checked many blog posts. Those posts which have buttons, are unable to update and preview. And those posts which have no buttons, can be previewed and update.

If I remove all the buttons from a post then i can check preview and update that post successfully.

I have disabled Gutenberg editor by enabling classic editor plugin.

I have also checked by activating genesis theme and checked the error but still the same error occurs. I have also checked by deactivating all the plugins but still the same error occurs.

If I check dev console in chrome then there are same type of 10 to 15 errors.

Here’s the screenshot link of error shown in dev console: https://prntscr.com/pu1yck

Please provide some solution.

I am not using Gutenberg plugin. I have latest version of WordPress (WordPress 5.2.4).

This becomes with many urls, so please give me solution as fast as possible.

Currently, I have deactivated “Q2W3 Fixed Widget” plugin from my site “WPressBlog” to avoid any issue.

I have installed it on my testing site where “Custom sidebars by WPMU Dev” plugin is also installed.

Here “Category” widget is marked as fixed widget and you can see that posts above categories have the large fonts and images.

Thanks in advance for the help!
