Hello,

I installed pressbooks in wordpress multi and pressbook but can’t import epub eBooks so i installed the missing epub validator (apt install epubcheck in Ubuntu 16.04).

If don’t installed the exports because i don’t Need to export.

but when i try to import an epub i still get the error page:

​[http://​](http://xn--zug)…/wp-admin/tools.php​ ​page=pb\_import&import=yes&\_wpnonce=5eeedff8a9​  
​ …  
HTTP ERROR 500

​when i try to export the epub Check box is even not available to Check also.

​I can´t import any epub… i miss something that i did not find yet in documentation.​

​Can any one Help? Somebody with the same problem?

Thanks.

It looks like your web host doesn’t include the [PHP ZipArchive module](https://encrypted.google.com/search?hl=en&q=php%20ziparchive%20module), which is required for Pressbooks to work with EPUB files (they are essentially specialized Zip archives). I suggest contacting your host and seeing if they can enable it for you.
