I'm using Zenphoto version 18.104.22.168  since about 7 years
Today I attempted to "refresh the database" because all of my images type MP4 add disapeared when viewing the pages of my web site
Then I went directly in the "media_images" table with phpmyadmin and discovered that indeed all of the records whose filename finished by .MP4 have disapeared and only the .jpg or .png are still there
Then I went directly with Fillezilla in the albums' directories on my server and surprizingly all the MP4 files are still there
Also, if I try to upload a new MP4, i.e. with the administration tool, it seems to do the job, but on closure a flash msg appears 1/2 sec to announce the upload did not work. Indeed no new video appears in the album. Doing the same with a jpg file works perfectly
Where is the bug?
Do I need to upgrade ? Is there any risk in such case to loose other images?
Or is there any way to rebuild correctly the table 'images' in the database ?
