Hi Low (or anybody else),
I have a similar problem to this one in the old devot-ee-support-forums. When I use Seg2Cat-tags they produce nothing (means: empty output). Template-Debugging returns a lot of pipes in the Snippet-Values ("||||").
In the mentioned thread Low wrote:
First of all, check if the correct category groups are selected in the extension settings. If the category in the URI belongs to a non-selected category group, then the empty string is correct output.
The category group is selected, the category exists.
Or else, enable the output profiler and look up the SQL query performed by Seg2Cat, which should look something like “SELECT LOWER(cat_url_title) AS cat_url_title…”. Then run that query in the SQL manager. If there are results in the SQL manager, but not from the extension itself, then there’s a conflicting extension somewhere, probably. Check which extension use the sessions_end hook as well and try to disable them to see of that helps.
Now I used the SQL-query, I think it's this one:
SELECT `cat_url_title`, `cat_id`, `parent_id`, `group_id`, `cat_name`, `cat_description`, `cat_image` FROM (`exp_categories`) WHERE `site_id` = '1' AND `cat_url_title` IN ('schule', 'lowseg2cattesttrash', 'deutschunterricht') AND `group_id` IN ('1')
and I get one result (the correct category).
Now my question is if there is any help for me identifying the problematic plugin. I have a lot of plugins installed, mostly commercials which I need (Assets, CE Tweet, FireMail, LowSearch, Rating, Playa, Threaded Comments, Wygwam ...).
I would appreciate any help very much, because it would be a useful delight for me to use Seg2Cat.
Thanks in advance!
