I have some problem with customer checking out.
When customer tries to make payment for over $300 or more than 100 items, it appears on the screen “Please be patient” and it just freezes.
The computer doesn’t freeze, only the screen freezes.
I contacted the payment gateway company and the server company, and they say they are not the problem.They say it’s the problem with the solution.
Also, when I try to update an invoice and try to notify user, the error message comes up.
The website cannot display the page
Most likely causes:
The website is under maintenance.
The website has a programming error.
What you can try:
Refresh the page.
Go back to the previous page.
This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.
For more information about HTTP errors, see Help.
Please help me solve this problem.
not sure if this help, but maybe increasing the memory limit might solve the problem?
Inside config.local.php, look for
// Set maximum memory limit
and maybe change the number to ‘128M’
