Broken categories editor?

[charm]

I added and edited many categories till now.
But when I tried to add one more category today, I received the wrong screen and nothing was done - see the attachment img file.

The same screen now, if I'm trying to edit any category.
This case took place, when catid=3375 was assigned to latest created category and I tried to add one more category.
Now I can do nothing with categories
Are there too many categories?

PP version 5.21

One more problem with categories - see image.
At the index page appeared empty categories unlisted in the category list.

I would suggest you turn off the cache in global options set it to 0 timeout.

Your cache list is too big to be saved in mysql. Your server mysql packet size is not big enough to allow that large of a packet to be saved thus your error. Not much we can do as far as the program is concerned since this error is coming from a server setting. Only thing you can do is not use the cache unless your host is willing to up the mysql packet size variable.

This setting was already set to 0 timeout. So it doesn't helps.

But "Number of minutes to cache information. Default is 10 minutes, 0 means no caching." helped. Thank you for idea!

Hello

Yes that was the setting I meant cache timeout. Not ipcache forget we have two cache switches so best to be explicit.
