Question Discuss plugin start new topic on each visit and wrong title per message

I am worried a lot about this problem ,
because it is creating double and triple pages ,
and google penalize the double content.
My forum dropped from 18% visits from searches to 13,7% and keeps dropping.
I dont know if this is responsible but i think so.

this is a very serious problem / bug of kunena for many people,
why nobody is interested ?

I'm sorry, but I was long time not here.
hm.. I see your problem now. In principle the error is fixed but if you delete a new created double discussion, it will created again. This problem happens, if you delete the discussion with the wrong thread id.
Example:
After the first visit the plugin has created a forum topic with ID 55
But with the bug in K5.1.1 you got in the database kunena_discuss table the thread ID 0 (therfore it has been created a new topic on each visit)..

Now the bug is solved and if you visit the article it removes the wrong table but nevertheless it creates a new topic with the next ID 56.
If you visit the article again, it creates the correct table but with continuous ID 57.

Now you have 3 threads (with ID 55, 56 and 57) but only the topic with ID 57 is correctly in the database (see image).
If you delete the topic with ID 57 it creates again a new topic with the next available free ID.

Solution:
Delete only the topics with the lower IDs (you see the ID in the browser address if you open the topic) or merge the topics to one topic.
Hint: You must upgrade your Kunena previously. This problem occur only with older discussions before upgrade to Kunena 5.1.3

Thank you for your time,
Kunena is updated but i still have the problem

Anyway deleting is not an option for me, every day i maybe have 10-15 new threads, if those they create 30-50 double threads i must be there all day to delete the double ones,

One other problem is that in the new created thread, there are only 3 dots,..., no link to the article or part of it.

Is there someone who can fix this ? NOT 4 FREE
1) Not to create a post in every visit
2) Instead of the 3 dots in the first post to show all article or link to it.

I am willing to pay for it

No support (paid or free) pity

if you remove the last id, then it should work normally, I couldn't reproduce the issue anymore.

810 thank you for your time,
i have about 7000 articles i dont know how many are the doubles ones generated all this time. How can i use your solution ?
Solution:
Delete only the topics with the lower IDs (you see the ID in the browser address if you open the topic) or merge the topics to one topic.

This can be usefull if you have 10-20 articles
