Ajax request fails after 1.8.2 upgrade

Get Help

Hello,
Xibo running on IIS 7.5 on widows 2008 R2
I have followed instructions to upgrade from 1.7.0 to 1.7.9 fine.
Then I upgraded to 1.8.2 and had no errors during the upgrade.
I can logon fine, access the dasboard, displays, templates, settings, many others, but when trying to view layouts or media, I have an ajax error.
404 error on:

http://xibo.mydomain.com/layout?draw=1&columns[0][data]=layoutId&columns[0][name]=&columns[0][searchable]=true&columns[0][orderable]=true&columns[0][search][value]=&columns[0][search][regex]=false&columns[1][data]=layout&columns[1][name]=&columns[1][searchable]=true&columns[1][orderable]=true&columns[1][search][value]=&columns[1][search][regex]=false&columns[2][data]=&columns[2][name]=description&columns[2][searchable]=true&columns[2][orderable]=true&columns[2][search][value]=&columns[2][search][regex]=false&columns[3][data]=function&columns[3][name]=duration&columns[3][searchable]=true&columns[3][orderable]=true&columns[3][search][value]=&columns[3][search][regex]=false&columns[4][data]=function&columns[4][name]=&columns[4][searchable]=true&columns[4][orderable]=false&columns[4][search][value]=&columns[4][search][regex]=false&columns[5][data]=&columns[5][name]=layoutId&columns[5][searchable]=true&columns[5][orderable]=true&columns[5][search][value]=&columns[5][search][regex]=false&columns[6][data]=owner&columns[6][name]=&columns[6][searchable]=true&columns[6][orderable]=true&columns[6][search][value]=&columns[6][search][regex]=false&columns[7][data]=groupsWithPermissions&columns[7][name]=&columns[7][searchable]=true&columns[7][orderable]=true&columns[7][search][value]=&columns[7][search][regex]=false&columns[8][data]=function&columns[8][name]=status&columns[8][searchable]=true&columns[8][orderable]=true&columns[8][search][value]=&columns[8][search][regex]=false&columns[9][data]=function&columns[9][name]=&columns[9][searchable]=true&columns[9][orderable]=false&columns[9][search][value]=&columns[9][search][regex]=false&order[0][column]=1&order[0][dir]=asc&start=0&length=10&search[value]=&search[regex]=false&layout=&tags=&userId=&ownerUserGroupId=&retired=0&layoutStatusId=1&showDescriptionId=2&_=1507821198134

or library?draw… for medias

I have checked access rights, url rewriting,…
Can anyone help me?

Thanks

You definitely imported the rewrite rules? There’s a section of the manual dedicated to it:
https://xibo.org.uk/manual/en/install_environment.html#url_rewriting

Failing that, there’s an unofficial guide here which may have a step you’ve missed?

The import failed, it does not convert any rules.
I had to manually add it to the web.config files at that seems fine.
I found out the issue:
Default Web Site-> Request Filtering - Maximum Query String (Bytes) to 4096 (otherwise you will get datatables.ajax error)
That was it!
Thanks a lot!
Have a good week end!
