My host had to migrate our server do to issues on their end. However, when I try to start my server with FE 1.4.4-1154 I get the following error. Based on what I'm seeing it looks like ZLib isn't installed or installed correctly, however, want to verify that before I ask my host to fix their server.

The error log mentions (l. 213) Unexpected end of ZLIB input stream so AFAIK, ZLib is correctly installed but the file passed to ZLib is either invalid or most likely corrupted.

Delete all files in ForgeEssentials/mapper directory.

@luacs1998 that seems to have done it. Thank you for the help.
