When I click shortcodes, I get a blank screen.

Is that the only one? Do the other options work?

I tried many of them and they do work! This is a great plugin!

So far, shortcodes is the only one that is not working.

Thanks. The code that displays the shortcodes is rather simple so I’m wondering of it’s a memory or timeout issue. Do you have WordPress debugging enabled? Do you have a lot of plugins that include shortcodes?

I don’t have debugging enabled, but the theme I have has a lot of shortcodes

It would have to be a ton of shortcodes to cause a memory problem but we should rule it out. Can you try a default theme like TwentyFifteen?

It works if I switch themes.

would you like to see the regex output?

Yes, good idea. What is the name of the theme?

the theme name is room09; https://themeforest.net/item/room-09-shop-multipurpose-ecommerce-theme/4638247

here is the regex output:

The theme advertises 300+ shortcodes which WordPress can handle but maybe the plugin cannot. I have not stress-tested it to know what the breaking point is in terms of page size and memory.

Do you have a shortcode that is not working or were you just curious what the plugin would show?

Curious as to what it would show.

When time allows, I will build a test environment with 300 shortcodes to see if I can modify the plugin to handle it.

Maybe dump it to a txt file when it hits X lines of data?

I’m thinking of capturing the output and flushing the buffer frequently. It’s been a while since I worked with that.
