Files (images) become corrupted after upload (?)

• Regression

I’ve being fighting with a weird phenomena since I’m trying to upgrade Tikis 20 to Tiki21.

My server is ClearOs 7 and I use php7.2 and file directory a storage.

I upload files, most appear ok and can be displayed.
Once in a while the upload is ok and the image appear in the file gallery but can’t be displayed in a wiki page sometimes the image doesn’t appear in the file gallery itself. ( I see a jpg or a png icon over the file in the file galleries)

To solve this:

1. I re upload (new version)
   Sometimes when I upload a new version (or replace since I set archives to none) and it work or sometimes I have a WSoD:
   
   
   
   I also get from time to time :
   +Error
   +Potential cross-site request forgery (CSRF) detected. Operation blocked. Reloading the page may help.
2. If not solved I delete the files in the file gallery and upload a new image (it create a new file object).

<img src="https://domaine.fr/dl18?display" alt="The image “https://domaine.fr.fr/dl18?display” cannot be displayed because it contains errors.">

Once everything solved, I do a files:check from the Tiki console.

It look ok (the extra file is certainly because of my numerous attempt during the last 3 days but not related to this issue).

I create a dump of the database and copy the Tiki themes folder and files folder on my local (I delete the old one) using Cyberduck (something I’ve being doing for ages) to create a local clone.

I check the files (OSX preview) and I can see the images properly displayed.
I create a new database and dump in the sql file (the database).
I create a new Tiki (git Tiki 20) and do the install process
I place the files folderand the theme folder where it should be.
I place the theme
I re update DB, re-index files, clear cache (you never know)
And check files using the console and I got the same than on my remote.
Look to me like a perfect clone to me.

But now, start the chaos. (can’t say there is a pattern) 😊

• A few images are not displayed on the wiki page.
• A few of images show the jpg or a png icon over the file in the file galleries. (images that are displayed in the wiki pages)

We are talking about a few files (53) and I’m enough experimented and wanted to report properly the problem (and I’m stubborn 😊 ) to solve one by one the issues. I doubt Tiki admin upgrading have the same "patience"...
