Chatgpt no longer accept PHP files with more than 100 characters

Hello,

Since the August 03 update, I can no longer ask chatgpt to update PHP files if the content is too large. I can only do it by code snippet. Before the update it worked perfectly. Now, as soon as I put in my PHP code, it tells me that something has gone wrong and doesn’t work. Can you please fix this bug quickly?
Thank you very much.
