Title: Critical Bug – Cross Posting suddenly starts creating thousands of duplicate topics/posts

Hello,

I have now been able to reproduce the problem again and I have found some very specific information that may help identify the cause.

I am using wpForo Cross Posting 3.1.6. After completely reinstalling wpForo and the Cross Posting plugin, Cross Posting initially worked correctly. I was able to create WordPress articles and manually cross-post them to wpForo, with exactly one corresponding topic being created.

Later, without changing the Cross Posting configuration, the problem suddenly appeared again.

I created a new test article (WordPress post ID 33758) and selected wpForo forum ID 22 (Konsolen News) for Cross Posting. After saving the article, Cross Posting started creating hundreds/thousands of duplicate wpForo topics instead of creating only one topic.

I checked the database afterwards. A previously working article (post ID 9790) contains the correct Cross Posting information, including the wpForo forum ID, the corresponding wpForo topic ID and the disabled status. For the new problematic article 33758, however, only the selected forum ID and the topic title prefix are stored. The corresponding wpForo topic ID is never written to the WordPress post metadata.

At the same time, wpForo keeps creating new topics in forum ID 22. I can see consecutive topic IDs such as 2232, 2233, 2234, 2235 and so on, all with essentially the same title. The process continues and can create thousands of topics/posts from a single WordPress article.

This makes it appear that Cross Posting successfully creates a wpForo topic, but then fails to save or recognize the newly created topic ID. Because the WordPress article still appears to have no associated wpForo topic, the plugin creates another topic, then another one, resulting in an endless loop.

The forum ID itself is correct. Forum ID 22 is currently my “Konsolen News” forum and forum ID 23 is “Allgemeine Game News”. Previously working Cross Posting entries also use these same forum IDs.

The particularly strange part is that this happened after a completely fresh installation. Immediately after reinstalling and configuring wpForo and Cross Posting, the functionality worked correctly. Only later did the endless topic creation suddenly start again, without me changing the Cross Posting configuration.

Could you please investigate why Cross Posting 3.1.6 creates the wpForo topic but does not save the resulting topic ID back to the WordPress post? This missing topic ID appears to be directly related to the endless creation of duplicate topics.

I can provide screenshots and database information showing the working and problematic posts if required.

Thank you.

I found out that this is caused by a combination of the WPforo Crossposting add-on and the WPforo to Peepso add-on from WBCom. I've opened a ticket with WBCom.

If you install the “WPforo to Peepso” add-on and then create a new cross-post, it doesn't work properly. maybe you can check togheter this issue for a good solution. 

It’s resolved you can close it this case! I reported everything to WBCOM, and they fixed the issue in the addon.

I would still have appreciated getting a response from the support team here. I’m planning to use wpForo as my main forum platform. I’ve already purchased two plugins and was planning to purchase more in the future.

However, at the moment I’m quite concerned about what would happen if I ran into another problem and needed support, especially after not receiving any response from the support team in my current case.

I hope you can understand my concerns.
