Testing your plugin out using integration and saw this at the bottom (regardless of activated theme) that broke everything that is supposed to appear after it:
_Fatal error: Call to undefined function the_webcomic_collection() in. . . ./wp-content/plugins/webcomic/-/php/integrate/loopstart.php on line 61
I'm apparently not alone as a Google Search turned up multiple incidents of it in the wild.
Went through every file searching for function "the_webcomic_collection" and looked in docs here, ultimately changed it to "the_webcomic_collections()" (plural) which stopped the error, but I don't know enough about your plugin to know if that edit actually fixes it.
(note: same undefined function is called on line 44 in "dynamic.php")
