Hello,
In order to improve site performance and guarantee site health, Wikia has decided to lower the maximum number of templates that can be transcluded into a page. Even if the templates are fairly straight forward, pulling them into a page can still be a technically costly process when the number of transcluded templates reaches the hundreds of thousands. Wikia is thus setting the limit at 300,000 template transclusions, a number that 99.99% of pages on our network fall below.
That said, some of the pages that are above 300,000 transclusions exist on this particular wiki. Once this limit is changed, pages which are "above" the limit will display an error on the page where the 300,001st template call is made.
General suggestions for effectively curtailing the number of templates on these pages is to divide the page into appropriate subpages or possibly to combine a number of templates together instead of reusing the same template over and over. Another common issue we see is “nested” templates (templates within templates within templates). Merging some of the code into a single, “flat” template will dramatically decrease the number of transclusions.
If you would like specific advice regarding any of these pages, feel free to leave a reply here and we will look into it further.
Here are the pages on your wiki that have template transclusions over the forthcoming limit:
