I don’t know since when it started, but I do know that last Sunday during the backup it still did work fine.
I can access phpmyadmin and do all kind of stuff, but when I want to export the database, I do get the following error (fast translation into English):
randomnamehere.sql.part could not be saved because the source file could not be read.
Try again later or contact the server administrator.
randomnamehere.sql.part konnte nicht gespeichert werden, weil die Quelldatei nicht gelesen werden konnte.
Versuchen Sie es später erneut oder kontaktieren Sie den Server-Administrator.
An export / backup via Webmin still works fine. I did try to check the logs, but didn’t find anything related to it. It’s possible I did check not properly enough. Also removing phpmyadmin and re-install it didn’t help.
I got no clue why that happens since nothing was really changed at the system, except package updates.
I am checking stuff and trying a few things and if I should be able to fix it / find out what’s the issue, then I will post it here in this topic.
Meanwhile I would be really grateful if someone knows how to fix this.
Thanks. I do prefer to use phpmyadmin, because its fast to use and useful for different things.
Currently I do the backup manually via webmin (direct interface in the database section) until I am able to fix it.
This could help as workarround to. ( take care for security)
Security is #1 priority in development of Adminer. Adminer does not allow connecting to databases without a password and it rate-limits the connection attempts to protect against brute-force attacks. Still, consider making Adminer inaccessible to public by whitelisting IP addresses allowed to connect to it, password-protecting the access in your web server, enabling security plugins (e.g. to require an OTP) or by customizing the login method. You can also delete Adminer if not needed anymore, it is just one file which is easy to upload in the future. Adminer had some security bugs in the past so update whenever Adminer tells you there is a new version available (ask your administrator if you could not update yourself).
I use this sometimes, it works also on may other “normal” webspace , i then rename the php extension after and also only 1 ip access. ( and use other filenames ofcourse)
I don’t know why, but I got the idea to test the php versions.
I switched back to 7.4 (from 8.0), and it did work then. I did switch back to 8.0 again and it broke the export function again. So there is definitely something wrong.
So know I just need to figure out whats the issue with the current php 8.0 an if its just a configuration issue or a package issue.
Since I got 7.4, 8.0 and 8.1 installed anyway, I did switch the phpmyadmin folder to 7.4 for now. That’s more of a workaround but it should suffice until I did figure out what exactly is wrong with the 8.0 version.
That might be a useful information for you too. If you do use php 8.0, then you might want to try to switch too.
And if you do use php 8.0, I would like to know if you did upgrade/update some packages before it started and/or if you did change settings in the php installation.
