Sooo, thinking this couldn't get any worse, it has.
Regarding the above post, I tried taking out menu item 271 and just use the link in the login module. Didn't seem to make a difference, will leave it like that anyway.
I tried to reverse this:
A. Put the "\3rd party\sh404SEF" file to
/components/com_sh404sef/sef_ext/ or in /components/com_uddeim/sef_ext/
B. and put the “\3rd party\sh404SEF\language\plugins\com_uddeim.php” to
/administrator/components/com_sh404sef/languages/plugins/com_uddeim.php
but can only do A. as not sure of the original content of B., tried it, made no difference, so put it back in.
So when I went to send a few messages to test the sh404sef url generation, I realised the Uddeim messages don't even send, to the intended receipient or to the outbox.
Next thing I noticed is that in configuration I have to save something twice for it to actually save with intended changes.
Why is Uddeim falling apart on me, was hoping to launch my website early this week.
I use default_ex template, installed an ssl cert this week - with the yireo plugin I set it so CB and Uddeim are using it, use sh404sef..
On my other site which doesn't have ssl, with a similar set-up to this site in question Uddeim messages don't send either.
Very stuck here, found nothing in the faq either.
