Some messages but not all do not appear when I click on them. They DO appear in the list of messages.
I can't access some emails. They appear in the list of messages but are empty when I click on them. When I try to forward them, the message is empty. I have tried updating Thunderbird.
Also at times when I click on one empty message, then another empty message, the topic does not change. It more or less refuses to go to that other message.

Check tools | Error console for errors that occur when you click on a message and post it/them here.
Then, check if starting in safe mode helps https://support.mozilla.org/en-US/kb/safe-mode-thunderbird
Right-click the folder, Properties, Repair Folder, and see if the messages are still blank. Repairing may take a while for IMAP accounts with many messages in the folder.
Hi, and thanks to you both for taking the time to reply. I'm not sure the Error message would help all that much, since it is in Danish. It basically said it was a Security problem. Meanwhile, I can quite check to see if Repair Folder helped, promising as it sounds. I had found the messages in an earlier MozBackup file and moved the unimpaired messages alongside the broken ones. When I clicked on Repair Folder, there was only one type of message there, an unimpaired one. But did it just toss out the broken one, or did it fix it and decide that the second version of the same message was unnecessary? In any case, many thanks, and I'm glad to know about the Repair Folder function.
Repairing a folder this way usually restores the correct relationship between subject headers and message bodies, but sometimes it makes an entire folder vanish if the corruption is severe. So I should have recommended you first back up your profile.
For IMAP folders, the best way to repair a folder is to perform a Real Fix: copy the existing messages to Local Folders, delete the mbox and msf files for the folder while TB is closed, then restart TB and allow the IMAP server to repopulate the newly created folder.
