It's very strange behavior. May be you can help me to resolve it:

Hi Vitaly,

The error is produced, because of mismatch of the controls/holders in the template and their parent ids. The error is thrown when the parent of one control/holder do not match correct child and docks cannot be arranged properly. Could you give us some steps( or send a screencast) that we could follow to replicate the issue here. After the page and controls have been added have you made some changes to the ContentPlaceHolders, layouts, removing and replacing templates etc?

The issue could happen in cases when you have removed some controls - physically deleted. When the page is loaded, it is divided on holders and the error says that when an element cannot get the siblings of matched elements.

All the best,

Hi Ivan,

We didn't make any changes and it's very strange. I've added Google analytics control at the master page via designer whithout editing master files. Could you provide some instruction how I can check/fix it into db?

Hi Vitaly,

It is not possible to check or fix this through the database you should recreate the page. If there are any steps that I can follow to replicate the issue, please let me know.

Sincerely yours,
