How can I reorder plugins at the end of single posts

Hi there,

each of those plugins are filtering the content, which makes that difficult to re-order.
Do the plugins provide an option to insert using a Shortcode?
If so you can use that method and add each shortcode to a Hook Element:

You would want to use the after_content hook and set your display rules for the posts you want them on.

To re-order their position you can change the Hook Elements priority - low (1) places them higher, higher numbers place them lower down the page.

Unfortunately non of the plugins provide shortcode.

How do I go about his now?

There isn't anything we can do to change that.
Each plugin will be setting its own priority for the_content filter which is out of our control. You may want to speak with the plugin authors.

Are there alternative plugins you can recommend that have shortcodes?

For the author box i believe this one does or at the very least provides the PHP Function which can be added using a Hook:

Social icons - search for GP Social Share

The other element you could leave as is.

That worked perfectly Thanks.

However, there is one more thing.
I used hook for this ad. https://prnt.sc/pmayfv

can I get it to display after the first paragraph of the last header of each post?

If so, how do I do it? Thank you

That's not possible unfortunately.

There are no hooks that exist between paragraphs.

are there hooks that exist between headings?
What if it comes after the last heading of all posts

Unfortunately not.

You can see all the available hooks in single post here:
