Reduced schedule during conference and annual break

We'll be operating with a reduced schedule from tomorrow and the next few weeks, as follows:

We'll be travelling and attending JoomlaDay USA from Tuesday April 22 to Friday April 25. Support will have extended response time during this period. From April 25 evening to Tuesday May 12 included, support will be closed for our annual break.

Don't forget to look up the documentation, including the videos, your answer may already be there! Likewise, be sure to check the Development versions area, in case your problem may already have been solved.

Hello,

I'm updating my site from J3 to J4.

I installed 4SEF and 4SEO and imported the data from sh404sef.

Now I want to uninstall sh404sef but get an error: Attempt to assign property "params" on null

Joomla is 3.10.12
sh404sef is 4.24.7.4352

I found a help-ticket, that reinstalling sh404sef helped, so I installed the last version of sh404, but it didn't help. I also tried to deactivate all sh404sef before uninstalling, but this also doesn't help.

I hope, you can help me with this.

Kind regards,

Michael Hertlein
