When using an AdBlocker some very special settings might cause problems with the fucionality of the web portal. Common problems are missing "Add" links or missing content. Try disabling those special rules and reload the page.
With default settings no AdBlocker will create any problem.
When not using an AdBlocker the problem might be your browser cache. Some functions might got changed after an update and need to get reloaded completely. The browser doesn't detect those changes and will load its cached content. This results in faulty functions or completely broken functions. Please clear your browser cache and reload the page.
