<![CDATA[OnlyOffice 1.26.0: Document editor loads blank in Nextcloud integration]]>Hi,

After updating OnlyOffice to 1.26.0, the document editor stopped working when opened from Nextcloud. The editor iframe loads correctly, but the document remains blank.

Browser console showed:

Loading failed for the <script> with source
"https://<onlyoffice-domain>/9.4.0-7ccb82f2cfdf2a42bd640661c9759f9e/web-apps/apps/common/Analytics.js"

Along with CSP warnings blocking scripts from the OnlyOffice domain.

Setup:

Nextcloud hosted on Hetzner Storage Share version Nextcloud Hub 25 Autumn (32.0.9)
OnlyOffice 1.26.0 (Cloudron package), underlying OnlyOffice Document Server 9.4.0
Connected via the official ONLYOFFICE app for Nextcloud

Resolution:
Downgrading back to 1.25.1 via Cloudron backup restore fixed the issue immediately, confirming the regression was introduced in 1.26.0.
Has anyone else experienced this?
Thanks

I noticed that OnlyOffice can be very picky with browsers and browser addons.
Can you try using your OnlyOffice from a clean Chrome based or Firefox browser?

But often I find after an OnlyOffice update I need to go back into /settings/admin/onlyoffice in Nextcloud and re-save the settings in there. Give that a try? 🙂
