Hi guys! Let me join this topic with the similar error. I have installed OpenKM 5.1.10 (build 7564) on open suse server and faced with the similar error: unable to see preview even for *.png files. I enabled full debug output and collected this into server-debug.log.gz file (attached). For your convenience the file finishes exactly after i pressed on 'Preview' tab and got an error about 'There was a problem with the conversion generation'. Could you please help me to identify the root cause of my issue?
Thank you in advance!
