Please fill out the template. We have no idea how you get the error, which version/apps/environment you are using.

have no idea what cause this issue. My issue come up after nextcloud migration. have one file name: .lastmodified in a folder, when i delete it, it come up again, this file no matter how i delete it, it come up again with the same name and date modified. when click on this file will get a error 404 page. I think this file stored in database but not in file system

I have similar problems with this error:

InvalidArgumentException: X-OC-MTime header must be a valid positive integer

And i found this on github:

Possible fix for that with these scripts:

But i have problems to get it working by this scripts.
So i tested this SQL command

SELECT COUNT(*) FROM oc_filecache WHERE mtime < 86400;

and got a number of files that have been affected.

As far as i can see from the logfiles, there are userdirs/pictures/…xxx.jpg files.
Seems coming from the android clients using autoupload feature for pics and videos.

Now my problem is that i don’t understand exactly how to use this

./ <path to storage folder without trailing /> <mysql|pgsql> <database host> <database user> <database password> <database name> <list|fix> <noscan|scan>

i chmoded +x the script "

and i used:
path to storage folder = datadir of the nextcloud confugured in config.php??
then pgsql because i use postgresql
and then next dbuser, dbpass
i have chosen to use the postgres unix socket instead of username and pass
in nextcloud so how to use the fix / repair commend with the socket info??
