Kentico 12 Home Page builder blank

S T asked on May 8, 2025 09:50

I have a strange issue, when loading the Page tab of my home page the page tab is blank. There is nothing in the event log and the only thing I can see in the console log is

https://websiteurl.com/cmsctx/pv/94eea617-b831-4711-b197-6dd41d4db069/culture/en-us/wg/a921cd50-5f1a-49b2-99bc937e4fcf1451/readonly/0/pts/638834417537371348/ea/1/h/1a4ffe1667d444f10491303fe1a74bb3d74f09c44ee8198d82bd59337fbbbbb1/-?uh=3f69b82198c23950df774f2e96ca6ad9f043a1b4f5d08a6212edafbdc1068c50&administrationurl=https%3A%2F%2Fdevcms2.insightsforprofessionals.com%2F 500 (Internal Server Error)

I've had a similar issue with https://admin.websitename.com/CMSModules/Content/CMSDesk/Default.aspx? paths and was resolved by adding an exemption in the cloudflare firewall but this was 403 forbidden.

The strange thing is that the homepage page tab is blank on the EN site, but f.e. FR and DE are working fine. Has anyone had this issue and where can I start to look?

Kentico v12.0.101

The issue wasn't caused by cloudflare or content. It was caused by faulty code in the RouteExtensions. When reverting DB to early points I could see that it wasnt DB or cloudflare or anything else until I reverted code, piece by piece to find that there was actual code in the RouteExtensions that messed up and redirected en-us/home urls.

Hi ST,

Does this page work correctly on the live site? Is it just in the Pages application in the administration interface that you are seeing a blank page?

I would first recommend checking the Event log application in the admin to see if there are any errors in there. If you find any, can you post them here? It could help identify the problem.

You could also check the browsers developer console by hitting F12 on your keyboard with you browser open, navigating to the Pages app and the page where you are seeing this issue, and then checking the console for errors.

Outside of that, have you made any recent changes to the project or have there been any changes to the hosting environment lately? Any changes to firewalls, security software, hardware, load balancers, etc.? Have you also checked to make sure your web farms are all showing as healthy in the Web farm application in the admin?

Page does work on the live site and in every environment its just the Page builder tab that doesnt work on Homepage in en-us, french and german work. And as I've said above event log is empty and the error that I've written above is from console log.

Okay, here's one more interesting thing, so en-us version of the homepage page builder is blank, but FR and DE work, so I went to the FR site, deleted the FR homepage, copied the homepage from the english site (thought maybe there was something on the EN homepage from widgets or content that was failing) but the EN copied homepage worked on FR and the Page tab and page builder were working fine. What could be causing an issue on the EN version of the homepage if its not the content on it or general routing ?
