Thankfully it doesn’t appear to have affected the frontend at all. * [Lobster01](https://wordpress.org/support/users/lobster01/) * (@lobster01) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404136) * Same here, just updated this plugin (which is wonderfull btw) and got the error message. No show on frontend pages and the plugin does work on frontend pages. * [ChefC](https://wordpress.org/support/users/chefc/) * (@chefc) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404138) * It appears this error is affecting my ability to add new pages/posts or edit anything on the site, when I try I just get a load of errors thrown at me in the backend regarding line 429. * [Lobster01](https://wordpress.org/support/users/lobster01/) * (@lobster01) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404144) * Well, I don’t have that problem. I have the error message and I can still publish any posts or pages. With and without the usage of the plugin. * [ChefC](https://wordpress.org/support/users/chefc/) * (@chefc) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404147) * Odd. * I’ve disabled the plugin for now and I can update my site once again just fine. * Hopefully this can be resolved soon so I can restart the plugin. 🙂 * [photoMaldives](https://wordpress.org/support/users/photomaldives/) * (@photomaldives) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404151) * same error message here, too. If it’s affecting other things, I think I’ll rollback till the fix is released. * (love this plugin by the way – keep up the good work.) * [Lobster01](https://wordpress.org/support/users/lobster01/) * (@lobster01) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404169) * Hmm the error of collapse-o-matic causes some problems with other plugins in the backend. For example: I use for my personal website a plugin for a bucket- list. The backend shows me normaly a list with categories and goals. With Collapse- o-matic and its error, the bucket list plugin does not show that list. It simply will not load it. The frontend shows the list fine tho. * I deactivated this plugin as well. Altho it’s a wonderful plugin, Im gonna search for another option to use a similar function on my website. Till the problem is fixed, I will not enable this plugin. * So lets hope there will be an update soon which fixes this error. * Plugin Author [Baden](https://wordpress.org/support/users/baden03/) * (@baden03) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404181) * CRAP! sorry about that. Update 1.5.6 is available and fixes this issue. We really need to fire the drunken pirate monkey that tests our code. Turns out it was not such a good idea. * [ChefC](https://wordpress.org/support/users/chefc/) * (@chefc) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404184) * Works like a charm, Thanks very much! * [Lobster01](https://wordpress.org/support/users/lobster01/) * (@lobster01) * [12 years, 5 months ago](https://wordpress.org/support/topic/on-155-update-admin-error-no-admin_init/#post-4404188) * Thanks for the quick fix.
