CNX import leading to HTTP error

Plugins
1

@brad Let me know if I should put this on GitHub instead.

@rootl can help with updating settings/more troubleshooting

When importing a CNX title, I’m getting an HTTP 500 error. We’ve updated our import settings and PHP upload settings, but even with single chapter zip files, the importer goes straight to an error screen (no loading/thinking time) on Chrome, and in Firefox I only see a white screen.

We’ve recently upgraded to the latest versions of both PB and the OpenStax plugin, so was wondering if this was a problem anyone else had experienced. (all current settings are listed below).

Other types of imports work as expected, and I’ve tried multiple OS titles and files on two different PB book sites and got the same error, both using the upload file option, and the Import from URL option. I don’t have access to another version of PB with this plugin installed to see if it is localized to our instance.

Hi Allison…yes please! I would also be looking for output from your web server…it will point us in the direction of the source of the problem…either in debug.log in /wp-content/ or (apache/nginx) log files.

thanks!

Greetings. @bdolor .

Alllison gets the “White Screen of Death” when she tries to upload an OpenStax file. I have tried uploading the same file and get the same upload screen, no white screen or error message.

Prior to PHP 7.3, I could have Debugging on from within wp-config. I am wondering if 7.3 doesn’t like this and log files and debugging should be from within the php.ini file instead.

These warnings are what repeatedly appear in the httpd error log:

I had to manually install the Zip package to work with PHP 7.3 . I tested both url and direct upload of an OpenStax zip and the import worked.
