Bug #80312

Updated by Josef Glatz over 2 years ago

h1. Problem/Description

In a project, where we started with TYPO3 master ~8.5.0-dev we often get a broken TYPO3 backend after a re-login is necessary.

h2. Scenario

In my case, this happens in following scenario:
# Im logged in in the backend
# My IP changes
# The login screen appears
# Login process works as expected
# At first glance all looks fine when the backend ui gets loaded

*but then*

# the last/starting module
# or pagetree could not be loaded

h3. However better than a Windows bluescreen, it looks like the following screenie (project name/Logo grayed out)

h3. What if you click on a module in the module menu (e.g. Web > Page Module)

The page module opens, but not within the frame

h3. Actual workaround

Manually reloading the whole TYPO3 backend before clicking on a module. (In some cases, that's not enough. If a simple reload doesn't work, an editor could click on a module, then press back button in the browser) module
