A problem in this section of this page: https://en.wikipedia.org/wiki/Statewide_opinion_polling_for_the_2020_United_States_presidential_election#Wisconsin was brought to my attention in this talk page thread: https://en.wikipedia.org/wiki/Talk:Statewide_opinion_polling_for_the_2020_United_States_presidential_election#What_happened_to_Wisconsin?

Basically, the polling section of the Wisconsin page was transcluded onto the general page for statewide polls.

The transclusion was broken for some reason, but functioned if the page was viewed in preview mode, and the transclusion was written exactly the same way as other functioning transclusions in other areas of the page. Neither I nor any other editors could determine what the issue was and I was advised to go here for help.

I manually copied over the text, but obviously a transclusion is preferable.

Thanks in advance

Looks like you hit the post expand include size limit. Basically the size of the wikitext of a page after all transclusions are transcluded, subst: are substituted (e.g. what you get at ) has to be less than 2MB.

If you hit this limit, there should be a warning at the top of the page when you preview. Possibly it might get auto-added to a hidden maintenance category as well

Sometimes people get around this for graph heavy pages using the <graph> tag, by using the Data namespace at commons, since that doesn't apply to the limit

That's it. Thanks, Bawolff. I didn't think to look for an error notice at the top of the page on preview.

Thank you so much!
