I’m not sure what the issue is stimming from. I receive a 403 error with and ONLY when I have Post and Page Builder activated. I have done everything in all the 403 error guides; checking SSL, (I don’t have a .htpaccess file), cleared cache both on my website and browser, used a different browser, used incognito, everything. Nothing is working. I disabled all plugins (which most are only Boldgrid plugins anyways since I haven’t had a change to really get far into building this site) and only activated the Post and Page Builder and when I don’t even change a thing or when I do change an element, I will hit update and get a 403 error.

When I check the error log for the website, this is what I get:
WordPress database error The regular expression contains an unclosed bracket expression. for query
SELECT ID
FROM Xg40xySX_posts
WHERE post_status IN ( “draft”, “publish” ) AND
post_type IN (“page”,”post”) AND
post_content REGEXP “[\[][^\]]+[‘\”, ]109[^0-9]+.*[\]]”
made by require(‘wp-admin/edit-form-advanced.php’), do_meta_boxes, post_submit_meta_box, do_action(‘post_submitbox_misc_actions’), WP_Hook->do_action, WP_Hook->apply_filters, Boldgrid_Inspirations_Purchase_For_Publish->post_submitbox_misc_actions_show_user_watermarked_image_count, Boldgrid_Inspirations_Purchase_For_Publish->create_array_assets_needing_purchase, Boldgrid_Inspirations_Purchase_For_Publish->asset_needs_purchase

I don’t know how to decipher that since I don’t know coding language well. And googling it brings nothing since it’s more unique.

It’s not just the home page and it’s only if a block has been added to the page. If I take one of the pages I want to edit and just publish or update, it works fine since there is no block on the page. It’s only when I add a block.

Please help! Thank you.
