my problem is:
I have a project in which I occupy the PdfMerger library with which I can join several PDFs in one, everything works perfectly, the problem is when I upload it to my Served where it thunders and marks me the error that it does not find the library but it's strange because I download my project again and it works again in Local , no matter how much I try and try to find the solution, I know that it could be what is generating the error because it does not mark anything just that it does not find the Class but only happens when uploading it.
Someone will have some idea why I might be failing, I would appreciate it very much !!!
