error from cron job on cliupdate.php concerning libpng

Hello,

I am running selfoss on a shared host.
In the last few weeks I am getting several times a day a error message from the cron job that is executing cliupdate.php

The cron job looks like:
/xxx/xxx/php /usr/xxx/xxx/xxx/selfoss/cliupdate.php

The error message is like this:
libpng warning: Interlace handling should be turned on when using png_read_image

It does not happen every time the cron job is running.

Looking in the logs of the shared host does not show me any hint, what is the reason of this error.

I have also checked the php config of the shared host, but this seems all fine.

Do you have any hint, where I can search or what I can ask the support of my hosting provider to solve the error.

Kind regards
Martin
