Cannot access Theme Customizer

Hi @alceomazza!

This AssetInjector.php file is used to add our CSS and JS files to the source of the page. For this we use output buffering, for which it is important when it is opened and closed, otherwise an error is created. So if there is a PHP error somewhere, that closes the output buffer sooner then expected.

If there is an error already on the page, our code could also result in this.
You should use the Health Check & Troubleshooting plugin, as you see here:
https://smartslider.helpscoutdocs.com/article/2006-how-to-use-health-check-troubleshooting-plugin
And check if you still see the same issue with only Smart Slider enabled with your theme, and no other plugins.
If you do, then please contact us here:
https://smartslider3.com/help/
and we’ll give you further instructions.

It seems it conflicts with a plugin developed internally by our company.
Although when only Smart Slider 3 is deactivated no errors or warning are printed inside the log, so we cannot determine what is causing the conflict.

We’ll contact you through https://smartslider3.com/help/
Thank you for the quick response

@alceomazza and @robertnextendweb I have the exact same issue. Can you let me know how the issue above was resolved?

BTW, my setup is

WordPress: 6.5.3
Smart Slider 3: 3.5.1.23
Astra: 4.6.15

OK, I solved the problem by adding

define(‘WP_MEMORY_LIMIT’, ‘1024M’);

define(‘WP_MAX_MEMORY_LIMIT’, ‘1024M’);
