Unable to create any file after activating templates after update to NC 21

Nextcloud version : 21.0.1
Operating system and version: Ubuntu 19.10
Apache or nginx version : Apache/2.4.41
PHP version: PHP 7.3.11

I just successfully updated my NC to 21. (from 20.x) Everything worked fine, NC is still up and running. Now when using the file browser and trying to add a new file using the “+” there is a new option “Set up templates folder” After selecting that a folder gets created containing a few files.

After this is done I cannot add any text document anymore. The message

Unable to create new file from template

appears. I already disabled OpenOffice with no noticable effect to that issue.

The logfiles clearly states that something is wrong there (“undefined”):

obviously something isn’t configured there that should be. But what is missing?

Is this the first time you’ve seen this error? (Y/N):Y

Steps to replicate it:

  1. Select “Set up templates folder”
  2. Try to create a new textfile

Not a solution but a workaround: I restored a snapshot before that click happened and disabled the template-menu-item via css:

    [data-action="template-init"] {
        display: none !important;
    }

Of course hiding does not really prevent anyone from triggering this nonetheless but all users of my NC are family members with good intentions :slight_smile:

Better (real) solution found :slight_smile:

I had to add the templatedirectory -property into the config.php. It seems that this is NOT optional anymore even though the sample-config still claims it to be.

Looks like I celebrated too soon. I don’t know why on very rare occasions creating a file still works, but most of the time it doesn’t. Rolling back to NC20

I did the entire tutorial with the official documentation and had the same problem, NC21 and Onlyoffice version 6.2.2.21

I did the same test with the NC20 and it worked 100%.

I just updated NC21 to the latest release (‘version’ => '21 .0.1.1 ',) and it worked to create new files :grinning:
