Title: Update Troubles? Backend Error, Custom Code Last modified: January 25, 2024 --- # Update Troubles? Backend Error, Custom Code * [ChrisFo](https://wordpress.org/support/users/chrisfo/) * (@chrisfo) * [2 years, 4 months ago](https://wordpress.org/support/topic/update-troubles-backend-error-custom-code/) * I think I installed the “Ultimate Addons Gutenberg Blocks” on two WP multisites( on shared hosting, rather low performance) just out of interest what is possible and if Gutenberg Core alone might not suffice. It seems some Update to now Spectra( by Brainstorm Force) has broken the setup: on one MS the plugin was not recognized anymore, did throw some casual backend error and I had to deinstall manually. On the second site after an update (not at the same time) the editing of Posts did give a general WP error. There I could deinstall the Plugin in the Backend. After that post editing did work again. I noticed after deinstalling all posts/ pages created after the installation have custom code also on standard tags like h2 : div class=”wp-block-uagb-advanced-heading uagb-block-435d82e2″h2 class=” uagb-heading-text”which standard Gutenberg does not recognize anymore for editing and get converted to HTML where the custom code needs to be removed manually for h2 etc. to work. I am not happy with how that all went and for now will stay away from Block editor extensions, at least such that I do not absolutely need. - This topic was modified 2 years, 4 months ago by [ChrisFo](https://wordpress.org/support/users/chrisfo/).

Please accept our deepest apologies for the recent update_(Version 2.12.0 – 22 Jan 2024)_ breaks. This was never meant to happen, and we are truly sorry for the inconvenience caused. * The error was due to an internal code conflict. Generally, we perform an extensive test before releasing an update but somehow this unforeseen issue slipped through. We will take steps to ensure this doesn’t happen again! * We have immediately_(within 3 hours)_ released a hotfix version to address the issue. If you use any version later 2.12.0, it should work just fine. * I understand how frustrating it was when you got the error. We take full responsibility and are committed to minimizing it in the future.  * **Regarding the leftover class:Generally, when you build a page with a block, that utilizes CSS based on its class. Removing the plugin manually from files won’t remove the class. This principle applies to all plugins. I hope you understand. * Can we work together to find a solution that works for you? Spectra is a great extension for Gutenberg, and I’m sure if you give it another try, you’ll love it. * Regards, * Mehedi Hasan, from Spectra team. * Thread Starter [ChrisFo](https://wordpress.org/support/users/chrisfo/) * (@chrisfo) * [2 years, 4 months ago](https://wordpress.org/support/topic/update-troubles-backend-error-custom-code/#post-17377270) * As written above I will avoid any unnecessary (Block) plugin at least on the main (uncommercial) WP sites I manage. I did not need Spectra WGB for a specific feature, it was just curiosity to test advanced Blocks. Maybe I will install and test again on strict Test WP sites. * **Regarding the leftover class:** I would understand if this was the case only for the blocks introduced by Spectra, but I did not expect this for “standard” blocks like headlines and images. This builds a dependence like from Elementor I’m seeking to avoid when installing content layout plugins. I need to investigate this further if I need to stay just with core functionality. * [Mehedi Hasan](https://wordpress.org/support/users/thebengalboy/) * (@thebengalboy) * [2 years, 4 months ago](https://wordpress.org/support/topic/update-troubles-backend-error-custom-code/#post-17381570) * Thank you, [@chrisfo](https://wordpress.org/support/users/chrisfo/) We hope you’ll consider Spectra for your other projects when it’s a good fit.
