mod_mime_magic: invalid type 0 in mconvert()., referer: on php log. The pdfJsViewer can’t open some files after migration from 2.4.5 to 3.0.2 
When I look to submission, the submission say that article was “published”, but when open the submission I can’t find the file final and the tab selected was “Layout Edition”.
Could you double check if your files exists and are correctly migrated in your files_dir?
Also, have you already searched after the similar issues in this forum, read them and tried the solutions from there? S. for example: Pdf viewer not see pdf file - #3 by ctgraham or Can't download or view pdf files - #25 by desilvarami

Hi @bozana , searching on repository I lost the files before migration, because they are not present on backup. So it’s, apparently, is not a OJS problem, but a server problem. I’ll continue to investigate and return if find some wrong. I’m grate for your help.
