1.6 + 1.7: Exception: Grav\Framework\Session\Messages

[pamtbaau]

TLDR:

• Accessing site on localhost:
  • Using http://dev-dev fails,
  • http://dev-prod and http://localhost/grav/site-dev succeeds
• quark/templates/partials/messages.html.twig throws exception on line 4: {% if grav.messages.all %}
• Exception + Stacktrace: See below

Config:

• Windows 10 + WSL/Ubuntu 20.04
• Path Grav installation: /path/to/grav/site-dev
• Defined hosts: dev-dev + dev-prod
• Apache: Virtual hosts/server names: 'dev-dev' + 'dev-prod'
  • Both pointing to folder /path/to/grav/site-dev
• Site accessible via:
  • http://localhost/grav/site-dev
  • http://dev-dev
  • http://dev-prod

Have been using above config for a long time (2 years?) without problems.

Steps:Grav 1.6.31 + 1.7.0-rc.20

• Browse to http://dev-dev
• Exception:

  An exception has been thrown during the rendering of a template ("Twig\Template::getAttribute(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Grav\Framework\Session\Messages" of the object you are trying to operate on was loaded before unserialize() gets called or provide an autoloader to load the class definition").

• Browsing to http://dev-prod
  • All goes well
• Browsing to http://localhost/site-dev
  • All goes well

Stacktrace:

Ran the tests many times and now some time later, it works....

[grantholle]

Having this issue on a fresh 1.6 install

[mahagr]

@grantholle Are you sure you installed a release and not just github source?

[grantholle]

Yeah it was from the releases. I ended up just using 1.7 as I was desperate to get it working.
