==================
Hi Community,

we have a problem trying to upload a file for an specific question. We have already check about permission, updates, almost everything. The upload function works, this was already tested.
The problem:

at certain point of our survey, there's a question, in witch the user should upload a file. If you click at the button "upload file", the screen is greyed and you can do nothing else, the upload window will show at the background.

 

I don't think this issue have to do with the survey itself, it's more a css problem.

The problem was already tested with different web explorers, Chrome, FF, Edge, Safari.

Just tested this with 5.3.4+220309 and the layer with the upload function is fine (above the greyed out area).

I will do a quick update and see if the problem was introduced in the latest version, or if it is not a general problem, but a problem with your installation.

Here the changes from 5.3.4 to 5.3.5. I don't see anything that might introduce this issue.
So I tested the upload question with LS 5.3.5 and I can't see any problem. Are you sure that your theme is a 100% standard "Fruity"-Theme and that there have been no changes to it? Check with another theme and see what happens.

I can't reproduce the issue.

1. F12 and inspect part
2. Can you check with Vanilla
3. Maybe SkelVanilla ?

indeed. it was the theme, but why? It is the standard theme and we didn't change the settings of this one.

We had a LS-Installation, witch because some php errors, and other ones, it was impossible to enable the "comfortable update" option. So, we made a manually update, as described in the documentation.

There was described: delete everything but 2 files and one folder. We made it, then we copy all the new files and run the after copy check process. At the beginning didn't work, because of ownership, we made the copy process as a root, but the script was waiting as a www user.

After that and some checks, we realized that our installation/upgrade wasn't completed. We couldn't upload anything and that was because some folder was missing.

With that in mind, and after checking my old backup, we found that the new installation has less folder than my backup.

I don't know why but, it could be that the manually update documentation is not completed? This is a seriously bug, if they recommend to delete everything and after that there is a lot to check because a lot is missing. Maybe after the upgrade is the default theme not complete at all and there some file/folder missing.
How to know? How to check?

Yes, it was indeed the theme. Thanks for the help!

You have the reason ?
Did the theme work before ?

Because if a theme work on 3.X.Y but not in 3.Z.Zb : it's an issue.

As I said, everything was ok until we made a manually update, after that some random events pop up, like can't upload anything or error messages because of ownership files and folders..

we followed the documentations and we made everything described, but the errors wasn't part of that. There is no mechanisms, witch could detect or check if everything is ok, so, at this point we are working with a system, witch in any moment could show some errors again and we have to deep search what could be.

About the theme, we dind't change anything, not yet, but we are thinking to change the logo, etc, etc. So the problem with the theme is so random at it sounds. But for any reason, it works.

That's why I said: Make sure you uploaded everything. Uploading via FTP sometimes skips some files.

There is no built in mechanism, because how will Limesurvey know that everything is OK? You need to make sure everything is uploaded. In my experience, the best way is to upload the ZIP-file to the server and unzip it on the server, and then copy the files from there to the right location on the server. The risk that anything is "lost" while copying is a lot lower. But at the end, when doing the manual update, it is up to you to make sure you copied everything to the right place.

1. Activate debug mode
