"Install Plug-in" -> blank page [Solved: faulty plug-in]

Update: A faulty plug-in was behind all this, "User profiles". All seems to work after deleting it.

-------

I can't install new plugins, or update old ones (install: even with manual upload). The button "Install new ... plugin" only throws a blank page.
Spartacus is set to github.
The Media Center view also only gives a blank page, not the overview of the media center content.

What am I doing wrong?

The IP is correct, host www.juggerblog.net resolves to 85.158.176.61 and port 443 serves the https protocol. Status code 500 Internal Server Error means the server could be reached but probably has some misconfiguration. A bad web server profile or already an error in some .htaccess file may cause that.

Hmmm. I tried a clean htaccess fiel (only with s9y basics) and it works when trying to install Sidebar plug-ins, but not Event plug-ins ... I should probably contact the provider.
Anything typical to ask them?

A blank page mostly means a PHP error terminating the script (without debug output), i.e. Error 500 (internal server error).

You could have a look into the logs or enable debugging to display error messages in the browser. $serendipity['production'] = FALSE in serendipity_config_local.inc.php should do the latter.

Sorry, no bug report shown. Only a completely blank page.

Still get an "Internal Server error 500" at the "Update plugin" and "Install new Event plugin" buttons, but *not* at teh "Install new Sidebar Plugin" (Yet, also at the "Update (sidebar) Plugin").
Even when clearing htaccess, and after upgrading to 2.1.5, using the standard 2k11 template.
Link displayed:

Code: Select all

https://www.juggerblog.net/serendipity_admin.php?serendipity[adminModule]=plugins&serendipity[adminAction]=addnew&serendipity[only_group]=UPGRADE&serendipity[token]=e6(...)f702c
Also, the "Done" button of the "Add media" functionality, when a media is chosen for an article (which works by itself) and should be inserted, doesn't respond, though all other buttons in the backend seem to work.

Other s9y installations on the same Server space (other domains) work fine.

What about the Apache/PHP-Error-Logs?

The call is registered in the FCGI log, but no error is shown in the Apache error log, sorry.

Workaround:I tried to copy a plug-in folder via FTP in the plug-in directory, but it doesn't turn up in the Plug-In list in the admin interface. Any caches to clear?

A plugin new in the filesystem is for serendipity not automatically existing, only when going to the "install plugin" page that spartacus fills as well it will be listed there.

Maybe that page works if you uninstall or deactivate spartacus?

Sorry, no dice. I deactivated, then deleted and uploaded a current version of Spartacus, still I only get a 500 error and no manually installed plug-ins available (both with Spartacus activated and deactivated).

So it should be either server-side, or due to some configuration error (should it?).

Blank page is almost always server side, and there are definitely error messages available somewhere. Just without them finding the issue - even if it's caused by a bug - is almost impossible.

Okay, I asked the provider whether they can supply some info on this.
Strangely enough, when I tried right now again to produce an error log entry, the Sidebar Plug-In install suddenly worked!
But not the Event Plug-In install. Neither any Update function :shock:

Now I am completely lost ...

Finally! Thanks to the provider creating a more detailed phperror.log, I could trace down a plug-in which caused all the trouble:

The "Userprofiles" plug-in was the baddie.

After deleting it, all works like a charm.

So: Check your plug-ins if you have a similar error ...

Ok, cool, now the updater shot down the Spamblock Bee and nothing works .... reuploading it ...

... I now get the error message in the Updater, "serendipity_event_userprofiles (2013-10-07 21.19)", even though teh User Profile plug-in has been deleted.
But since both Plug-In Updater and Installer now work, I can live with that :)

Thanks onli and Thh and the others for passing by and helping to solve this.
