Technical Errors

error_500_general

Problem: I get Error 500 when trying to access Studyflash

Solution: Hi,

I'm sorry you're seeing an Error 500. This is usually caused by a temporary browser caching issue.

Please try these steps:

Open an incognito/private browsing window and sign in at studyflash.ch

If you can log in there, return to your normal window, clear your browser's cache and cookies, and then sign in again

These steps typically resolve Error 500 issues.

Let me know if this resolves the issue or if you need any clarification!

Solution: Hi,

I understand how frustrating this Error 500 message can be when trying to log in.

Sorry you're running into that error 500 message.

Here's the quickest way to resolve it:

Open an incognito/private browsing window in your browser

Navigate to studyflash.ch and try signing in again
