Jetpack White Screen 500

  • Trying to set up WordPress for the first time on this domain. Pretty new to WordPress but it sounds like JetPack is one of the most important plugins to use. Have installed other plugins, no issues. When JetPack goes to register, I get a white screen after putting in my credentials. I also get the white screen if I try to unactivate JetPack, so the only way it can be uninstalled is by deleting files from the server.

    Online searching has helped me troubleshoot. I have confirmed that I have 128 memory. I also went in and uninstalled any old PHP versions and updated MySQL. I now have MySQL 5.5 and PHP 5.3 and no old versions of PHP.

    Still having the same problem.

    Was checking on the forums here and saw that someone had the same problem, even the error 500 issue in the error log, but no resolution yet.

    Any ideas on what to try next?

    Error log is below:

    Oh, forgot to mention. I have also disabled all plugins and tried JetPack with nothing else. Didn’t help, same error.

    I also tried different themes. Didn’t help, same error.

    Re-upload a fresh, unpacked, copy of the plugin’s folder to wp-content/plugins using FTP or whatever file management application your host provides.

    Doing that now. Is there a difference between installing through the interface and uploading files?

    Uploading manually can significantly reduce the risk of damaged files.

    Okay, done. Same errors.

    Is it possible that there is a needed PHP extension that I don’t have installed? I tried to find a list of which PHP extensions to activate but the only decent list is from a few years back. Seems like it would be a simple thing to list, but…

    500 error after logging in to the site. I know I am logged in too, I can go back to WordPress.com after the white screen and I was definitely logged in.

    Lines 41 and 124 seem to be the issue, and I know nothing about programming.

    Not with those errors. Did you delete the old jetpack folder before uploading the new one?

    What installs the ctype_digit() function? Sounds like, if the server could parse that, it would work.

    Okay, my questions answered it. I looked up ctype. Part of PHP. Installed it. Works now.

    ctype_digit causes an error 500 when installing JetPack if the PHP ctype module isn’t installed.

    Thanks, helped me too!
