 * Hey guys,
    anyone encountered the problem when installing plugin?
 * After uploading the zip file we’re getting this:
    **The package could not be 
   installed. PCLZIP_ERR_BAD_FORMAT (-10) : Invalid End of Central Dir Record size:
   17**
 * It’s a custom plugin, it works fine with all other WordPress installations we’ve
   tried. The zip file itself should be fine, the space on the server also. We kind
   of ran out of ideas.
 * Thanks!

 * It is possible that WordPress doesn’t have enough memory (not space) to unzip.
   It can also be caused by a plugin.
 * I suggest checking memory usage on server and trying disabling all plugins.

 * PCLZip is the fallback ZIP archive processor in WordPress. Unlike the PHP Zip
   extension (which is what WordPress uses if it’s available), PCLZip does not need
   to read in the entire archive to process files, so it uses less memory. While
   the error could be memory-related, it’s unlikely.
 * How did you create the ZIP archive? Did you use a standard ZIP archive tool, 
   or did you use a custom tool such as 7-Zip? Are you able to extract its files
   using a standard un-ZIP command-line tool?
