Error: "Oops, something went wrong while loading" [SEE APPROVED ANSWER]

I have the same problem. I use Safari and need the extension to work. Did anyone found a solution until 1Password team fixes the issue and releases hopefully - a quick fix / new version within a day?

Just woke up to the same issue on Chrome. For some reason Safari and Firefox were unaffected

@scottfulmar suggestion worked. Thanks!

Did somebody find a solution / work-around for Safari?

Unfortunately uninstalling / reinstalling did not work.

Same issue here. I followed scottfulmar's feedback (Thank you very much!) and uninstalled the plugin, closed browser and used Settings>Browser "Get 1Password for your browser". As Edge is my default, the "Edge/Add-On" page opened (not Chrome) and I installed again the Edge addon. After this, it works again. So finally, reinstalling the addon is the solution I would suppose.

Edge Add-On Link I was redirected to:
https://microsoftedge.microsoft.com/addons/detail/1password-%E2%80%93-passwortmana/dppgmdbiimibapkepcbdbmkaabgiofem

Have had the same issue in all my 4 browsers with the plugins.
For being able to reply here to this post, I created an account via the 1password application. Looks like creating an item fixed the issue in all the browsers :-D.
Really strange behavior.

Edit: Sorry, was to fast. The described solution worked for me in Edge, Chrome and Firefox under Windows. Brave still had the issue. I had to go the way @scottfulmar described. Uninstall plugin, restart browser, install plugin. After that, Brave plugin also works again.

Someone in another thread found a fix, at least for Chrome. Uninstall the extension from Chrome, then close Chrome, open 1Password app, go to Settings>Browser, click on "Get 1Password for your browser." This will take you to the Chrome webstore's page for the extension, where you can reinstall it. The extension should work properly after that.

As above reporting using Chrome browser, extension autofill doesnt work at all. Also extension and bottom of screen full app are not in sync anymore. I.e. locking extension and app worked in unison, locking one would lock the other and vice versa. Getting OOPS message. tried rebooting and pretty well what has already been listed before. Quickly losing confidence.

Adding more details, clicking Reload 1Password does not solve the problem. Restarting browsers as well as restarting the computer does not solve the problem either.

Thanks for the offer to continue...I honestly appreciate it, steph_giles, but I'll pass for now and try again later. FWIW, even though both Macs are brand new, I completely deleted every single file associated with 1Password per your own instructions, then reinstalled it (a second time) on both new Macs, using a new download installer file. Same exact result. The Mac app installs fine, the Safari app "appears" to install fine, the Mac app works fine, but clicking the locked 1P icon in Safari invokes the login screen for about a half second, then it invokes the login screen for the Mac app.

Hey LarryMcJ,

I'm so sorry for the trouble, that is definitely not the expected behaviour and I'd be more than happy to continue troubleshooting to get things working as they should be for you.

I respect your decision but if you would like to give it another try, the logs I requested above would be really useful for us to see exactly what is going wrong and get things back on track.

Let us know if there is anything else I can help with at all.
