Aligatores, I removed this because it looked like a spammy link. Your post itself is okay and your others look fine as well - I hope you are not just a very smart spammer. If you are not, please just avoid looking like one.

Theerer is a config option on how many articles are on the frontpage, which you could set to 1. It's under Configuration -> Design and Options -> Entries on Frontpage (or similar, the oen where I checkes is not in english. Is that what you are looking for?

Which is very strange. That is what I'd expect to be empty, given the error message. You could try to place a commentpopup.tpl from 2k11 or from default into your theme.

Well, that's at least a hint. In that PHP file comment.php, one of the last lines is this: $serendipity['smarty']->display(serendipity_getTemplateFile($serendipity['smarty_file'], 'serendipityPath')); That's line 230 at my test installation, which I think is unchanged. Add a debug output there: echo...

And if you visit yoururl/blog/comment.php?serendipity[entry_id]=2813&serendipity[type]=comments directly, do you get a blank page?

The theme should fall back to the 2k11's file, you do not need to have a specific one in the theme.

The comment.php has not that many calls to Smarty. You could try them out - and just try to comment. The log does not contain the GET parameters, does it?

The strange thing is that a fatal error should also be visible in the blog itself, by producing a 500 error. Maybe it only happens when visiting seldom opened pages, like the 404 page? The only idea I have right now to test it: Add $serendipity['production'] = 'debug'; to your serendipity_config_loc...

The CKEditor Plus plugin has not seen an upgrade in a very long time. It's primarily developer is not active with s9y anymore and no one has picked it up - and in the meantime, the CKEditor installation that is bundled in the core got improved. It is quite possible the code of that plugin is no long...

Definitely.

The missing v=... could impact how the cache works, but it should not break anything in everyday use.

Possible. There haven't been that many database changes though. My guess would have been that the Javascript that open the overlay to select the categories was broken. That can happen if e.g. an outdated plugin got called.

Is the new install working fine now?

Nermax, what hoster do you use?

As far as I can see those plugins could need a new maintainer. I could help with looking at how they interacted with the core - there might be something that needs fixing there. If you or someone else are interested in getting those plugins to work again, dive into the code and ask questions :)

Eventuell hat dein Browser da automatisch ein Passwort eingegeben, mit seiner Passworterinnerungsfunktion.

Da hat wahrscheinlich dein Browser den Passwortschutz aktiviert, der in den erweiterten Einstellungen unter dem Texteditor zu finden ist. Wenn du die Funktion nicht brauchst kannst du sie in den Plugineinstellungen vom serendipity_event_entryproperties ausblenden. Ich gehe davon aus dass du vorher d...

Hi, yes, that was German (it's the german subforum :) ).

The ckeditor plugin got abandoned and is not necessary. The best way to use the WYSIWYG editor is to uninstall it and to use the editor as provided in the core, without any plugin.
