Today I read the article KB0118248 and remembered my blog post from 2018 . I also checked the attached aha idea where a comment states that you can use iframe for Youtube. Despite what KB0118248 incorrectly states, it is absolutely possible to embed videos in HCL Connections blogs and wikis using the HTML video tag as demonstrated in this post.

I received several complaints from users who struggle to identify uploaded images in the File Uploads section of blogs. This happens because pasted images get cryptic filenames like editor_image_ + UUID, making it challenging to identify and delete unused images.

I haven’t touched the Connections scripts for a long time, but I recently made some minor updates to fix compatibility issues with newer versions and added small scripts to speed up configuration. I also got the documentation script running from the menu.

The last weeks I had twice the issue of a huge homepage database with HCL Connections. Both systems weren’t installed by me, but I reviewed them.

So I know this issues quite well since I faced it the first time years ago. This always happens when you migrate Connections environments side-by-side, and you forget to remove the old search nodes.

I had some issues with PDF export functionality in HCL Connections the last weeks.

The server became unresponsive multiple times due to high load from PDF exports. To quickly address the issue, the simplest solution is to disable the PDF export feature by configuring the icxt.pdfexport.access.requiredrole property in the Resource Environment Entries.
