Ok.
I increased the php memory size with adding “php_value memory_limit 128M” in the .htacces file.
Maybe this can help someone else.

– replacing all WordPress file / Enfold theme files
– adding “define(‘WP_MEMORY_LIMIT’, ‘**M’);” with 32M, 64M, 128M etc.
– deactivate theme and activate ( in various combinations like : switching -> change language -> switch back to Enfold and so on )
…
The curious thing is that the whole site works, everything is displayed in german, so the language change worked fine.
Just the Ajax Search doesn´t work and I am not able to enter the theme specific settings ( including the Slider settings )
