ownCloud login failure after YunoHost update

I still cannot use ownCloud after updating to the latest YunoHost release. I’m completely stumped here. The only lead I have is the error message I posted above. Somehow my ownCloud sync apps (Mac and Android) still work, but I can’t access the webpage. Also, when I try to visit a previously shared link, I actually get a webpage to load, but it says the following error:
