Class ref in pre-verified class resolved to


Have anyone here got an error “class ref in pre-verified class resolved to unexpected implementation”

some of my user have this error, when they trying open the app.

I search google and found out that problem most likely from third party library reference added two times.

any suggestion what i can do to solve this ?



Well what extensions are you using and are there two of the same?


But it only happened to few of my user, most of all dont have a problem…


I don’t even remember to have made an extension… :thinking::thinking: :rofl::rofl::rofl::rofl:


hahahahahahahahaha :rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl:


do you have a link to that KleyberTool extension, I never heard about it…

usually in case of library conflicts you would get an error while building your app…



Me neither, @Taifun.


I saw you asking the same question in another community…
so the question is: which distribution did you use for building your project?
you might want to ask only in the corresponding forum then, because that problem might not be relevant for another community
thank you


Andres Cotes made that for you @Kleyber_Derick


Ahhhh ok… LOL Didn’t remember that!!!


thank you @Peter
I already had it in the extension directory as “Encode MD5 extension” :wink:



yes, I am using that extension to have MD5, even though the MD5 is not secure by default, but it just suit my purpose.
