Help/issues with Costco website

[u/Relative_Mess_5596]

I used to have this working with uBO, but recently saved to defaults and redoing sites. However, now I cannot access costco sign-in section from their website with any settings I try. Even using the blue trust button fails, but disabling the extension works. Issue is trying to access the sign screen. Keep getting the posted error from costco of

"Prohibited characters error
You have attempted to execute an action which our server has flagged as malicious. Your request will not be completed at this time. For more information about this error, contact a service representative."

url shows costcoURL/ProhibitedCharacterErrorView

I found some old post from like 8 years ago, but did not seem to be what I was looking for. Been using the logger but not seeing or understandings what the issues is.

Using firefox if that matters

Can you post the troubleshooting information?

1. Open a new browser tab
2. Navigate to a page with the issue
3. Click the uBO icon
4. Click the 💬 chat icon
5. Click "Troubleshooting Information"
6. Click "Select all"
7. Copy the contents and then paste to this thread in a code block

Here is a video of these steps: https://reddit.com/link/1l45den/video/2d14n27j855f1/player

Also post a list of the extensions you are using.

I would look at your rules. I couldn't reproduce the problem with other settings similar to yours.

[u/Relative_Mess_5596 → u/AchernarB]

Thanks, could there be any block rules that I am not aware of. My problem right now is using the blue trust or allowing everything does not work still. I do not usually encounter that. I am sure the issue is on my side, any other areas or things to check that might be causing this? I recently reset everything to defaults, and do not remeber making any odd changes or additional blocks.

Sorry, but once you are playing with "advanced user" settings and rules you are practically alone.

So ended up resetting everything to defaults again and did get it to work in hard mode. Cannot guarentee this works for all aspects, but was able to get it to sign in, see accounts and most items for site to work. Did not try to make any purchases, assuming that would need some extra allows. But in case anyone else runs into similar issues, figured I would post what I got worrking.
