Hi, I've written a plug-in which works so far, but I'm not able to save settings to the _addondata folder. I'm on Window 10 with Apache and all other plug-ins are saving without any problem with the same save code. Any suggestions?

Difficult to say without the plugin-code. Not all plugins need that folder.

Normally You can save to /_addondata/subfolder (if _addondata exists)

MyGuestbook - plus and the Spamfilter-plugins use such a folder.

P.S.

But plugins only use these _data - directories if they are installed from the web and not if the are manually installed under /addons_

Therefore You should use cms-variables like $addonRelativeCode and $addonPathCode  for pathes. This is of course not for a beginner in Js and php - or : much to study....

Sorry, wrong post :)

Sorry, the culprit was a stupid typo.

But I have a other question. Is there any documentation or tutorial how to make a plug-in editable in the sections?

 

The only documentation is in the above plugin-link and the Git-wiki. 

For the rest You will have to study plugins with this feature (which also use hooks).

Which sections do You mean ?
