PHP errors upon logging a QSO

[msmcguire]

Hi. I'm really enjoying Clouldlog, but recently have been encountering some PHP errors upon logging a QSO. The errors read as follows below. The QSO data is recorded in the log, but each time it throws these errors at the top of the window. Any help is very much appreciated. Thanks.

Hi Mike

This refers to us setting cookies, are you getting this all the time and are you running any plugins in the browser, certainly haven't changed any part of this code in a couple of years so quite an odd thing.

Other thing is haven't recently changed PHP version or anything like that.

Peter.

Ok, so I looked at the post from AndreasK79 below and experimented by adding the following line of PHP code to the index.php file.

<?php ob_start(); ?>

This seems to have corrected the issue. However, I'm not entirely sure what this does or if it might create other problems. Also, I'm not sure if this will be overwritten with automatic updates. Please advise at will. Thanks.

@msmcguire seems like you figured out one way to fix it from the link. This will be overwritten with automatic updates. Something is going on with the code, but I haven't tried to figure it out. Perhaps Peter will figure something out after looking at the link I provided.

@AndreasK79 thanks for the help on this and for looking into it. Do you know if others have been reporting this issue?

[AndreasK79]

@msmcguire not that I'm aware of.

Hi,
I just installed Cloudlog on my server (running PHP 7.3). I also got this warning every time I log a QSO. Also, it was shown after creating my Station Profile.
The fix proposed by @msmcguire worked for me - would be great if we could verify that it has no unwanted side-effects, though :)

This might clear some things up:

Thanks for this, but I'm not sure what to do with it. Perhaps Peter can help further with this information?

Just to say that I've made some changes to how cookies are set (Its order) I'm not convinced it will resolve the issue but looking for feedback from people who see this problem
