Error white page issue and no access to wp-admin

Hello @thornyrose

If you’re seeing this error either suddenly (no specific task was done to cause the error) or frequently, try deactivating all plugins to rule out a plugin-specific issue and try switching themes to rule out a theme-specific issue.
Otherwise, here are three ways to increase PHP’s memory allocation:
1. If you can edit or override the system php.ini file, increase the memory limit. For example, memory_limit = 128M
2. If you cannot edit or override the system php.ini file, add php_value memory_limit 128M to your .htaccess file.
3. If neither of these work, it’s time to ask your hosting provider to temporarily increase PHP’s memory allocation on your account.
(in the above examples, the limit is set to 128MB)

Thanks

@aezazshekh thank you so much for your reply, but as I mentioned I have tried all of the above solutions, my memory limit is 128, I have tried disabling and enabling plugins and themes, and nothing works. Also, my cart and payment page are not available too. When I go to the cart, it just shows a white page and on top is written “error”.
