LLMS.txt not generated due to ABSPATH in certain Hosts

Hello!

I found that on hosting environments where ABSPATH points to a read-only directory (such as WordPress.com and Pressable), the llms.txt file isn’t generated.

On these platforms, ABSPATH resolves to a system directory that contains only the WordPress core files and doesn’t allow write operations. As a result, AIOSEO can’t create llms.txt or llms-full.txt, and the “Generate” button in the LLMS settings stays greyed out.

Using dirname(WP_CONTENT_DIR) instead of ABSPATH fixes the issue, since it points to a writable path.

Could this be reviewed for a future update? It likely affects other managed hosts with similar setups. We reported a similar issue to Yoast, and they promptly fixed it in a later release, so hopefully AIOSEO can apply the same improvement here.

As a workaround, we applied some code changes directly in the plugin file and it worked, but I believe it would be best to have this handled natively in the plugin instead of using a custom patch:
