Error I just received after making a post in the Technology forum under the Elten English Community

I was making a post in the Technology forum under the Elten English Community, and after the post was submitted, where I'd normally expect it to be displayed right away, I received this error:

ELTEN Script '__eapi{eapi}' line 866: NoMethodError occurred.

undefined method `size' for nil:NilClass

After that error was printed, the program itself crashed and needed to be relaunched. No idea what's causing it, unfortunately. This has also happened to me a couple other times when trying to browse forums, but I thought at first that it was something on my end. Now, however, I'm not so sure. This has occurred on version 2.5.2.7 of the application.

I've got that same error even trying to read posts in a thread. So I understand.
