These are the types of error messages I get. The WW I installed was the one on nexusmods, since every link in the first post of this thread is dead.
Don't use Nexusmod, most of the mods that you're going to find there are outdated, that's why you got this kind of error msg, read the error txt file from MCCC command center to have a better clue of your obsolete mods + ModConflictDetector + Sims 4 Mod Manager . Install your mods manually in your mod's folder inside the sims game in your document's files.
You can also download the last version of wickedwhims here, if you don't find the last version on F95, but normally you get th enew version here faster (i don't know how you ended up with a really old one...):

(yes the website is in russian but just do a bit of research about how to translate and search on google or it's going to piss me off if you're that lazy, also the files themselves are the english one)
