libpng warning: iCCP: known incorrect sRGB profile

[Jade D]

Hi all,

Hoping that you guys can assist. Last night I noticed that the system cron had not run in 3 days and after much fiddling around I managed to locate the error how ever my attempts to locate the cause have been unsuccessful

When running the cron using the command (yes its windows, and its not supported, 🙂 but its worked up until now....)

C:\>c:\apps\php-7.0.14-nts-Win32-VC14-x64\php.exe -a "D:\XXXXXXXXXXXXXX\crons\cron.php" "all" "-F" "-vvv"

The following is being returned

My searches lead me to these threads which kind of indicated what the issue is, ie corrupt png profile so I removed the logo from whmc's general settings > logo url and reran the cron and no luck, same issue

No matter how many times I run the cron it is not getting passed this step and is spamming those particular clients

I have managed to resolve the issue by doing the following,

Downloaded ImageMagick portable and copied mogrify.exe to the server based on the recommendations made here 

https://stackoverflow.com/questions/22745076/libpng-warning-iccp-known-incorrect-srgb-profile

Then used the code below to create a batch file that would run mogrify recursively against all folders on the server after reading the following

https://stackoverflow.com/questions/29587837/imagemagick-batch-convert-all-pngs-in-subdirectories-to-jpegs

The batch script looks like this

d:\
cd D:\Domains\XXXXXXXXX\wwwroot\
for /r /d %%a in (*) do mogrify "%%~a\*.png"
