Open Source Document Management System | OpenKM

I am currently using OpenKM 6.3.0 Community Edition on the following system:
- Operating System: Linux Mint 21.3

I have encountered an issue where the file preview for Word documents, images, and PDFs is not working. I have configured the necessary settings in `openkm.properties`, but the previews still do not display.

Here are the steps I have taken so far:
1. Installed SWFTools for PDF conversion.
2. Verified that the paths in administration > configuration parameters are correctly set.
3. Restarted the OpenKM service after making changes.

However, the preview feature still does not function as expected. I would appreciate any help or guidance on how to resolve this issue. Thank you!

Log shows no errors

Should be shown an error in the log file but in what you have shared there's nothing.
* Stop the openkm
* delete all files in the logs folder
* Start openkm
* Try to preview a document

Then share the log file as you have shared now.
Check in the console and network in the browser tools for some error

Still haven't written a thing.

* ¿Can share screenshot of the browser when trying to previewing the document?
* Check with browser tools the console and network ( clean just before trying to preview the document )
