I'm trying to migrate to a server from my local environment. I keep getting Internal Server Error. I have the latest version of 3+ of CraftCMS. Everything works fine locally but on the server not so much. Here is what I'm seeing in my Craft log file.

    2019-02-08 05:02:35 [-][-][-][error][yii\base\ErrorException:8] yii\base\ErrorException: unserialize(): Error at offset 352 of 93525 bytes in /home/kinoliclients/public_html/jbbls/cms/vendor/craftcms/cms/src/services/ProjectConfig.php:997

The PHP log file gives a bit more information.

Also, just for context. I had the site running on the remote server but then did an update (the one that said, this is a difficult update). The update put it in a vegetative state (internal server error). The same update worked locally, so I then copied the files and database to the remote server hoping that would fix the issue remotely. However, it didn't. Was their a new PHP extension requirement or something, that might have done this?

  • Fly by guess: have you checked if a YAML file was created for projects and if this exists in both places? – joomkit Feb 8 '19 at 14:18
  • No, their is no YAML file. Does PHP read that for something? I don't have that file locally where everything works, so I can't imagine that's the issue. – kinoli Feb 9 '19 at 0:13
  • Try clearing out the Craft storage/runtime/cache folder. – Brad Bell Feb 11 '19 at 3:21

It ended up being an unserialization issue. After exporting the sql file, I updated it with the new domain. The serialization part within the craft_info table needs to have the correct character length in front of the domain. Fixing that fixed my problem.
