[10:52:52] Hi, I installed the extension LiteSpeedCache but when I debug it's shwoing the following error [10:52:53] Notice: Undefined offset: 828 in /extensions/LiteSpeedCache/LiteSpeedCache_body.php on line 200 [10:54:18] And I have the following codes at the end in LiteSpeedCache_body.php [10:54:18]  199               $output->addWikiText( $text ); [10:54:19]   200      } [10:54:19]   201  } [10:54:44] Can someone please tell if there is any solution to this? [11:10:10] Anyone aware of this error? [14:52:18] It looks like that's not LiteSpeedCache_body.php you've pasted, so you are likely looking in the wrong place for your error [14:58:38] 828 is the Module namespace from Scribunto, so it seems like something in LiteSpeedCache isn't expecting that [21:55:30] I have a question about the wikitext here: https://en.wikipedia.org/w/index.php?title=Putrescine&action=raw&oldid=39755708 [21:55:45] What is the purpose of using {{{mol_mass|88.15}}} rather than just 88.15? [21:59:43] ungato: That's template code. Probably someone substituted a template instead of transcluding it [22:00:42] What do you mean by transcluding? I'm new to wikitext [22:01:18] And by template code, you mean you'd normally see this in the definition of a template? [22:01:21] you can standardize some part of a page and use it in multiple places. we call those templates and we call the reuse "transcluding" [22:01:34] on Wikipedia, the infobox is a template that is transcluded [22:02:14] that syntax identifies a parameter mol_mass that could be used to vary the specific display on one page, while having a default of 88.15 for places where you don't care to change it [22:03:48] in case, say, you want to display the isotope with molar mass 89, you'd put `|mol_mass=89` in the page using the template
