We're so sorry if problems appear on the site - we are trying to find out why some TABs doesn't seem to be visible for some users. For most users it works as usual, but we've had a couple of people telling us the TAB is not visible. I don't know what browser you're currently using, but could you try another browser (safari, google chrome, firefox) and see if the problem still appears?
If there are still problems, please follow these steps:
Clear Browser Cache: Sometimes, outdated or corrupted cache files can interfere with loading. Please try clearing your browser cache and reloading the page. (As mentioned above) Try a Different Browser: The viewer works best with modern browsers like Google Chrome, Firefox, Edge, or Safari. If you're using an older browser, switching to one of these may solve the problem. Update Your Browser: Ensure your browser is up-to-date. Older browser versions may not support all the features of the PDF.js viewer. Disable Browser Extensions: Certain browser extensions (e.g., ad blockers, privacy tools) can interfere with the PDF viewer. Try disabling extensions temporarily and reloading the page. Check JavaScript Settings: The PDF viewer relies on JavaScript. Make sure JavaScript is enabled in your browser settings. Test on Another Device: If possible, try accessing the page on a different device or network to see if the issue persists. This can help determine if the problem is related to your specific setup. Inspect Console Errors: If you're comfortable doing so, you can open your browser's developer tools (F12 or right-click and select "Inspect") and check the "Console" tab for any error messages. Feel free to share those with us for further investigation.If none of the above steps help, please let us know what browser and device you're using (e.g Chrome, Version 131.0.6778.205)
