Describe the issue or problem
Article PDF view shows PDF corrupted.
When I removed the LIB folder and uploaded a fresh LIB folder in my directory, it’s working properly, and I can view my uploaded PDF file.
But the same issue faced the next day: the LIB folder is again corrupted.
What application are you using?
For example, OJS 3.3.0.11
