im using namecheep server to host my website and i have a page where you can create a post . On the create post page i use a WYSIWYG summernote extension for the textarea. when someone uploads a large image into it and then clicks the submit button to create a post nothing happens. This does not happen when i test it on local host, i can add alot of high quality images on localhost. I tested to see if uploading a really small image works on the server, and it does. so i thought the problem must be because of the size of the images.
so i updated these values on cPanel to:

memory_limit    768M

post_max_size   128M

upload_max_filesize 1G

but that didnt work so i dont know what the problem is....

This is the code for the page for creating a post
and This is the code it runs when you click submit on the creating a post page

im not sure whats causing the problem.... whats annoying is that this only happens on the server so i cant debug it on localhost :(

i guess the question is,
1. do you know whats causing this problem on the server?
2. is there a way to debug when im on the server?

additional info:
this is the table that stores the post

    $queryT2 = "CREATE TABLE IF NOT EXISTS Posts ("

        . "post_ID INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,"

        . "creator_ID INT UNSIGNED NOT NULL,"

        . "title VARCHAR(1024),"

        . "content longtext,"

        . "latest_updat_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,"

        . "dateCreated TIMESTAMP DEFAULT CURRENT_TIMESTAMP)";

content is where i save the large images and all the post content
