Hello,
There are lots of questions in this thread, I am trying to answer them one by one.
Q1) transparent header,
How do you set the header as transparent in Astra theme?
Please provide detail steps to duplicate the same problem in a fresh WP installtion, if you want a CSS solution, please provide a live problem page URL and working page URL, so I can test it in my Chrome browser.
Private message box enabled. thanks
Q2) H1 tag
I assume we are talking about Toolset Heading block, it is possible to setup a H1 tag, see my screenshot h1-tag.JPG
Q3) it still opens up with Toolset Blocks
Since you are using Toolset Views plugin, so you can still use Toolset Blocks feature,
You can try these:
1) Dashboard-> Toolset-> Settings-> General, in section "Editing experience", enable option:
Show both the legacy and Blocks interface and let me choose which to use for each item I build
2) Edit your content template again, there is a link for switching to classic editor:
Use the Classic Editor for this Template, see screenshot classic-edior.JPG
Q4) Dashboard-> Toolset-> Settings-> General, in section "Editing experience", you can use option: Show only the legacy interface for designing with shortcodes
Q5) See the answer of Q3 and Q4
Q6) Toolset Blocks plugin is based on WordPress builtin Blocks editor(Gutenberg editor), both Blocks editor and Elementor editor are page builders, it is not recommended to use them both to design the same page/post, it might conducts unexpected result as you mentioned above.
