Okay Thanks

once again same issue

@emmazz
Fixed. You should increase maximum allowed memory size, otherwise you will not be able to check for duplicates that already exists.

is this duplicate checker with with title only ? or with description ?

because i have same titled ad with multiple description ( multiple persons ads )

@emmazz
Both, title & description are compared, but only on user level.
This means that you can have 2 identical listings from different users.

Is the duplicate checking available only for logged in users?
As I'm posting anonymously, identical (title, text, email, category etc.) listings and they aren't marked as duplicate/spam.

Edit: Also tested with a logged in user and it still doesn't work. I can post as many identical listings as I want.

Also, 'Refresh listings and show duplicates' returns 'No duplicates found on this page.'

What could be the issue?

Testing on localhost: PHP 5.6.25 - Memory 128mb, Apache 2.4.23, MySQL 5.6.32, Osclass 3.7.1, Mcfly Theme 1.6.0 (on/off), HTML Editor 3.0.1 (on/off).

It is comparing listings posted from same email only. If it would compare all existing listings, it would cause page freeze and slow loading due to high PHP workload (technically not possible).
