[barati_a]

hi my friend

after I updated my site to 1.7.4 I have many problem and can not access to some part of my site

for example when I open modules

I have this error

1.6+ third party modules are not upgradable to PS1.7+.

When you upgrade from 1.6+ to 1.7+ it upgrades the DB and the default modules, no theme or third party modules; for those you need 1.7+ compatible versions.

I had the same issue after upgrading from 1.6.1.16 to 1.7.4.4.

The issue was clearly caused by 3rd party module. With the friendly URL turned on in [Traffic & SEO], clicking on [Modules & services] would redirect me to 404 - page not found. By turning the friendly URL off, I would be able to see the Symphony error (exactly the same as in the original post). 

I fixed it by deleting advancedeucompliance folder from modules folder at the server. I would have to search for AeucCMSRoleEmailEntity (the class from the critical error) to identify, in which module it was used. Then I simply deleted the whole module folder.

Don't forget to click on the [LOG] tab in the Symphony error page to see full error details. By default it shows no details, only the following error.

Compile Error: Cannot redeclare class AeucCMSRoleEmailEntity

return Db::getInstance()->executeS($sql);

After deleting the module folder, the [Modules & services] section started working instantly. You can then turn the friendly URL back ON.
