Error Could not open `espo` cache

[Nishan Perera]

Hello,

I have upgraded my espo version from 7.0.9 to 10. After that, I got an error like "error 500" with a blank page. Web console showing "Could not open `espo` cache."

I've attached a screenshot for reference. I appreciate your prompt support for the same.

Hi, might be something wrong with your server permissions, as said in the mentioned file (manager.php) after line 644:

/**
* Returning true will cause situations when files are created with
* a wrong ownership. This is a trade-off for being able to run
* Espo under a user that is neither webserver-user nor root. A file
* will be created owned by a user running the process.
*/

Because of this a cron job could not be executed. Have an aditional look into your server logs, might help.
