“Application error: a client-side exception has occurred” usually means a browser extension or cached data is breaking Tella in your browser. Open Tella in an incognito or private window first; if it works there, disable extensions or clear tella.tv’s cache and cookies.
Quick fixes to try first
1. Try Incognito/Private Mode
Open Tella in an incognito or private browser window. This bypasses extensions and cached data that might be causing issues.
-
Chrome: Ctrl+Shift+N (Windows) or Cmd+Shift+N (Mac)
-
Firefox: Ctrl+Shift+P (Windows) or Cmd+Shift+P (Mac)
-
Safari: Cmd+Shift+N
2. Try a different browser
If you’re using Chrome, try Firefox or Safari (on Mac). Sometimes browser-specific settings or extensions can interfere with Tella.
3. Check VPN or security software
Some VPNs, firewalls, or security software can block connections to our services. Try temporarily disabling:
-
VPN connections
-
Corporate firewalls or proxy settings
-
Antivirus web protection features
4. Disable browser extensions
Ad blockers and privacy extensions sometimes block scripts that Tella needs to function. Try disabling extensions temporarily, especially:
-
Ad blockers (uBlock Origin, AdBlock Plus)
-
Privacy tools (Privacy Badger, Ghostery)
-
Script blockers (NoScript)
5. Clear browser cache and cookies
Cached data can sometimes cause conflicts. Clear your browser’s cache and cookies for tella.tv:
-
Go to your browser’s settings
-
Find “Privacy” or “Clear browsing data”
-
Select “Cookies” and “Cached images and files”
-
Clear the data and restart your browser
