Hi, after update from Seblod 2.3.9.2 to 3.0.3 following problems appears:
Some articles in the backend are no more connected with Seblod. If i open this articles only ::cck::1751::/cck:: is displayed in the standard Joomla editor. All this articles also are not displayed in the frontend. I only made the update, no other changes. I've tried the whole day to fix it, whitout success. My System is Joomla 2.5.9. Do anyone know this Problem (and a solution)?

UPDATE:

I still don't know the reason why this happend, but found a workaround. In db search for '#__cck_core'. This table contains the connection between Joomla and Seblod. If there is an entry with the item id of the article in the column 'pk', the article will be open with Seblod. After adding the missing rows manually, everything work fine.

------------------------------------------

I also found following problem with export an app folder: Warning: require_once(/.../plugins/cck_storage_location/config/config.php) [function.require-once]: failed to open stream: No such file or directory in /.../libraries/cck/base/install/export.php on line 986

thank you
