Hi Kyle - so due to your help I found the problem and know how to fix it ...but...at the same time I think I have found a real issue concerning language plugins when you install more of them at the same time:
You remember: I triggered the backend-query in 'Community Builder'/'Tools'/'Check Community Builder Database' .........the following warning appeared:
"Warning: 1 entries in Community Builder __comprofiler_plugin are duplicates.
plugin=de-DE pluginid=594"
...so your hint was correct that there are at least 2 rows in the table '_comprofiler_plugin' with the same value in the 'element' column (I found 2 records with the value 'language' in the 'element'-colum)....BUT THE INTERESTING THING was the following: ....the first record belonged to the german-plugin and the second record belonged to the english-plugin!!!
...so my second question was: From where does this element name 'language' come from ...and I found that this information is inside an XML file:
..as follows the corresponding XML-file for the german plugin
<?xml version="1.0" encoding="utf-8"?>
<cbinstall version="1.0" type="plugin" group="language" xmlns:xsi="
www.w3.org/2001/XMLSchema-instance
" xsi:noNamespaceSchemaLocation="file:../../../../../validation/ahawow.xsd">
<name>de-DE</name>

...so far so good... and as long as you only install 1 language plugin at the same time you don't have a problem...BUT if you install at least 2 language plugins (for different languages) and with the same:
<filename plugin="language">language.php</filename> XML code inside, you get this warning when you run: 'Community Builder'/'Tools'/'Check Community Builder Database'
...I saw that there are a lot of language plugins with the same
<filename plugin="language">language.php</filename> sequence inside:
...to fix this issue it is necessary to change this code-sequence in the XML-file...
e.g:
...for the german-plugin change to:
<filename plugin="german">german.php</filename> ...this will result in element = 'german'
...for the danish-plugin change to:
<filename plugin="danish">danish.php</filename> ...this will result in element = 'danish'
...what do you think about this ?
