When any user or even the administrator posts a topic or responds, you need to wait many hours to post again.
If someone has to post before waiting for many hours the error message appears:
You are posting too quickly. Slow down.
I'm using Wordpress version 5.2 and the plugin is in version 1.6.1
Please read this support topic:
Several of my users are reporting it, I haven't experienced it myself. And, for the record, I believe that resolved those date issues after the last set of posts.
I don't see anything on my server logs that would explain it and I have a pretty fast server - a cloud VPS with dual processors and SSD drives. I don't have any caching on the server, I removed it and just use the WPForo cache. That resolved some earlier issues back when I set up the forum.
And BTW, I would NEVER post here unless I was convinced that an issue exists - if only one member had reported it then I'd assume that it was just an intermittent problem. But I've now had several different members report it to me.
Again, I haven't experienced it myself, with my own forum or this one. But my members are generally quite technically proficient, after all, it's a forum for people who build robots!
And I had seen the thread on the WordPress forum before I posted here, I usually try and resolve things myself instead of crying "wolf". If I were a member of the WPForo team I'd be somewhat concerned about the comments that many of the members there were making.
I'm also having the same issues and was told that they would be fixed in the last update. They weren't. The posting too quickly issue is a HUGE problem. The timestamps aren't fixed either.
