Upgrading 9.0.8 to 9.1.3

[czcpf]

I upgraded from 9.0.8 to 9.1.3 and espo just loads a blank home page. no error in logs. The only error I see is something on the frontend:

[Error] Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating 'e.cacheTimestamp')
(anonymous function) (espo-main.js:124:12209)

UPDATE 1: I also just did a fresh install of 9.1.3 and as soon as the installation finished the home page did not load with the above error. No other error in logs.

UPDATE 2: I also did a fresh install of 9.1.0 and as soon as the installation finished the home page did not load with the above error. No other errors in logs.

UPDATE 3. I then did a fresh install of 9.0.8 and everything worked after installation as expected.

Hi czcpf,

Unfortunately, I can't reproduce your issue.

My local environment: Apache, PHP v8.2.28, MySQL v8.0.41.

Upgrade EspoCRM from v9.0.8 to v9.1.3 - home page opens successfully without console errors.
Clean installation of EspoCRM v9.1.3 - home page opens successfully without console errors.
Clean installation of EspoCRM v9.1.0 - home page opens successfully without console errors.
Clean installation of EspoCRM v9.0.8 - home page opens successfully without console errors.

Please tell me where you download the archives for installation? Perhaps you install EspoCRM via Docker? I would be grateful for details.
