# Bug Summary After I installed Starter Templates by Astra themes, I encountered this error that prevents loading the website but WP control panel is working. > Fatal error: Uncaught Error: Maximum function nesting level of ‘256’ reached, aborting! in C:\Users\Ad2048\Local Sites\arcedu\app\public\wp-includes\class-wp-block-parser.php on line _83_ > Error: Maximum function nesting level of ‘256’ reached, aborting! in C:\Users\Ad2048\Local Sites\arcedu\app\public\wp-includes\class-wp-block-parser.php on line _83_` What I have found that Starter Templates plugin installs “Ultimate Addons for Gutenberg” plugin, and when I deactivate this plugin, the website works! # Steps to reproduce 1. I tried to add `xdebug.max_nesting_levels` [As in ths topic](http://community.localwp.com/t/error-with-preload-local-fonts-in-kadence-theme/25195/2) and set it to 500 and even 1000 but no results. 2. Deleted and created the website multiple times, but still problem exist (even restart computer too). # Environment Info - What Operating System are you using?

Hello @Abdo - thank you for bringing your question to the Local Community! 👋 Do you need Xdebug enabled? If not, you could disable it using the following steps & see if the error persists: > For Local, that would look something like this: 1. Open the `php.ini.hbs` file for a site, under `sitename/conf/php/php.ini.hbs` 2. Comment out the lines with a semi-colon that have Xdebug in them 3. Restart the site to reload the configuration ![Shared with CloudApp](https://p-DgFRdw9.t2.n0.cdn.getcloudapp.com/items/d5uOy40X/ce10df87-0748-48fd-b0a7-be53f3b688ba.jpg?source=social&v=1a3baca288f2a1c99b53eeb6fb8317cc) Let me know if that helps!

Hello @sambrockway , thank you for responding. I have did what you mentioned in Notepad++, saved it, stopped and restarted website and another error showed up to me: > Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in > C:\Users\Ad2048\Local Sites\arcedu\app\public\wp-includes\class-wp-block-parser.php on > line 461 > > There has been a critical error on this website. ![image](https://us1.discourse-cdn.com/flex019/uploads/lwpforums/original/3X/a/3/a36e42768cfb684d3066f48a2c9abed1b84053bb.png) I restarted my PC too, but didn’t work. Also I noticed that when I refresh the page, the line number in the error message is changing randomly! EDIT: I have 12GB of memory. ---

These types of errors may be due to infinite loops in the code somewhere. In this case, possibly the plugin you’ve designated. ---

Yes, @Abdo - I’m thinking (as @afragen mentioned) that plugin you mentioned might be causing some issues on your site - especially since the issue is resolved when it is disabled. Is that plugin necessary? Sam ---

Hello there, Thank you for taking time. I solved the problem, it looks like the theme I used has a problem, the contact block in the theme showed as “Block has been deleted or is unavailable.” in editing mode. but removing that block solved the problem! Thank you @sambrockway @afragen for your support. ---
