Cannot update YourLogo logo file

[tim.thornton@teamsur]

Hi,

I'm having problems changing the default company logo file. I select the file (a standard JPG, 52x255) and click on Save, the screen refreshes and nothing is changed.

I'm running on Windows Server 2012 R2 using IIS and PHP 7.1 with Prestashop 1.6.1.14.

I'm new to Prestashop, ad not a PHP programmer, but this is what I've tried and found so far:

- Obviously enough, the file is not being uploaded to the img folder

- I've changed access rights to full control for Users and IIS_USERS in case it was an access rights issue, but no change

- I've set '_PS_MODE_DEV_', true in defines.inc.php and an error message flickers across as the page refreshes, too fast to read but using screen capture it is:
Deprecated: Function mcrypt_decrypt is deprecated in  ... Rijndael.php on line 68 which looks like just a warning

 

Anyone got any ideas on how to fix this or where to look further?
 

Tim

This appears to apply to all image files, as the same problem occurs with images for the image slider.
