We weren’t able to reproduce the javascript error. * Which issue are you experiencing? Please share step by step details to reproduce it. * Suggestion: clear cache and go to PublishPress Blocks configuration and click save (no need to make changes). See if makes a difference. * [amberadmin](https://wordpress.org/support/users/amberadmin/) * (@amberadmin) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14069890) * Hi [@htmgarcia](https://wordpress.org/support/users/htmgarcia/) , * I just updated to the latest version of the plugin (2.5.5) this morning. After doing it I started noticing the error for the first time while trying to update an old blog post. * On a step by step basis, what I do is: 1. Open blog post 2. Click on any part of it 3. Get error * I just did what you suggested and also tried the fixes described [in this article](https://thomas.vanhoutte.be/miniblog/wordpress-fix-the-editor-has-encountered-an-unexpected-error/). None of them work and I am still getting the same error (I did not try the last fix as I am using the Gutenberg editor and have disabled the classic editor.). * As I said previously, once I deactivate the PublishPress plugin, the error disappears and I can edit the posts. * Hope this is clear enough, but please let me know if you have more questions. * Thank you for your help in advance. - This reply was modified 5 years, 3 months ago by [amberadmin](https://wordpress.org/support/users/amberadmin/). - This reply was modified 5 years, 3 months ago by [amberadmin](https://wordpress.org/support/users/amberadmin/). * Plugin Author [htmgarcia](https://wordpress.org/support/users/htmgarcia/) * (@htmgarcia) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14070056) * Thanks [@amberadmin](https://wordpress.org/support/users/amberadmin/)! * Unfortunately I’m not able to reach the error following the 3 steps.

I suspect it may be some stale, cached frontend asset as the underlying cause. Also `cache flush` (WP CLI) and trying with a different browser (would further confirm the caching hypothesis). * Plugin Author [htmgarcia](https://wordpress.org/support/users/htmgarcia/) * (@htmgarcia) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14070794) * [@strarsis](https://wordpress.org/support/users/strarsis/) cache seems involved.

Maybe clearing these ([https://developer.wordpress.org/cli/commands/transient/delete/](https://developer.wordpress.org/cli/commands/transient/delete/)) fixes the issue? Transients should be deletable by design, so I think this is safe to try. For me, this bug only appeared and could be reproduced on the production system, not on the development one. * Plugin Author [htmgarcia](https://wordpress.org/support/users/htmgarcia/) * (@htmgarcia) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14076716) * Hi [@stevebab](https://wordpress.org/support/users/stevebab/), this seems to be a different issue related to Advanced Accordion block. * We noticed you have an open ticket in our support system. Please downgrade to [2.5.4](https://github.com/publishpress/PublishPress-Blocks/releases/download/v2.5.4/advanced-gutenberg.2.5.4.zip). * Looking forward to help you * [stevebab](https://wordpress.org/support/users/stevebab/) * (@stevebab) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14076877) * Downgrading fixed it for now. Thank you. Let me know when we can try a solution for the new version. * Thanks! * Plugin Author [htmgarcia](https://wordpress.org/support/users/htmgarcia/) * (@htmgarcia) * [5 years, 3 months ago](https://wordpress.org/support/topic/block-error-breaks-editor/#post-14091409) * A new version has been released addressing the issue related to Adv.
