XF 1.5 When uploading "a server error occured please try again later"


Active member
Only with specific images im trying to upload. Both are PNG, but one of 9,6mb failed and one of 6,8mb worked to upload.
I tried some more images and it seems the error occurs at images larger then approx 8mb.
I am using the sonnb add-on to upload images, but this also occurs when attaching images in xenforo itself.

Please try enabling debug mode temporarily (via config.php) and attempt the upload. Is there a different message? (Please disable debug mode then.)
