Since a few months already I have frequent issues loading the Whatsapp sidebar. Instead of the Whatsapp page I only get to see markup gibberish.

It happens randomply like once a week or so. Sometimes after a fresh restart of Opera and/or Windows, sometimes after Operat has already been running for days. I cannot reproduce it. In rare occasions I can fix it by clicking the reload button on the top left. Closing and restarting Opera may or may not fix the problem.

I haven't noticed the issue with the Twitter sidebar.

Any ideas how to solve the issue or pinpoint the cause? Especially, as the error only occurs occasionally, I'm not sure what of the things I tried, did or did not resolve it.

Opera 70.0.3728.189 (but has been the same for many previous versions)
Windows 10 home 1909

It seems Opera does not set and/or read cookies with https connections. I noticed that with Wikipedia where I get constantly redirected to the mobile site (de.m.wikipedia.org/...) when using a safe connection while I stay on the desktop version when using a normal connection. I believe WP safes the preference in a cookie. Can someone confirm this? It might be that something else is the reason for this behavior. Any way around it?

hmm. That works with speed dial but I cannot drag search engines anywhere. Well, maybe it comes back in a later version. Adding engines already helps a lot. Thanks.

That works. Thanks. But is there also a way to delete the predefined entries?

Hi,

is there any way to modify the search engine list (add, delete, modify entries)? Or can I alternatively adapt the list to another language? I frequently use the search for Wikipedia but want to get results from the German branch.

Thanks.
