If you feel you found an issue in CKEditor 4, we will be grateful for letting us know. Before you create a bug report, however, please read our guidelines on how to do it properly and most efficiently.
# Reproduce on Demo Page
To eliminate the chance that the issue might be caused by some third-party software or your customizations, try to reproduce the issue on CKEditor Examples first.
CKEditor 4 Examples samples are always running the latest editor version. Please note that if the problem was fixed in one of the releases that succeeded the version you are using, you will need to upgrade your CKEditor 4 installation as we do not backport fixes.
Most of the issues are reproducible on samples. If you have a different case though, no problem. Go ahead with the next steps.
# Avoid Duplicates
Before you file a new issue, make sure your issue has not been reported yet. Use the search page to check it.
If the issue has already been reported, just add a 👍 (+1) reaction to it.
CKEditor 4 is in active development, so there is a chance that we have already fixed your issue in the current code base. You should thus also test it on the latest Nightly Build.
