Did you checked the uploads folder permission on server. Set the uploads permission and that will fix your issue.

Many people are using the wordpress name in there domain. If not then wordpress need to purchase all the domains which are related to wordpress. Which they think these domains are important.
This is all about public interest.

I am matching with all the trademark criteria.

1. I am promoting the wordpress
2. All my code and site is under GPL license

What I am planning to add the my site links in my RSS feed. If I add the twitter follow URL and some my site self urls in my article then this problem is can be solved.
But I am not sure. Please I need more advise on this.

Yest I did. Still I facing the issue

You need check following article.
https://wordpressapi.com/2010/02/01/show-related-posts-wordpress-post-plugin/

$.42 is very high price. I can go for vps or dedicated server.

Just put following code in your style.css file and date and other info will hide.
.meta{display:none;}

which wordpress version you are using. there is inbuild functionality to show excerpt in home page. you just need to edit your theme files.
use the the_excerpt() method in index.php file.
Just replace the the_content(); method to the_excerpt() function.

You need to Download theme file and upload into wordpress admin. that will solve your issue.

use following code in page template.

<ul>
<?php
global $post;
$args = array( 'numberposts' => 5, 'category_name'=> arts );

$myposts = get_posts($args );
foreach($myposts as $post) :
?>
<li>
<?php the_post_thumbnail();?>
 <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>

the only issue with your code is concatenation of variable.
use following code.

$path = get_bloginfo('template_directory');
$path = .$path . '/images';
update_option (upload_url_path , $path );

Use the following code.

get_the_post_thumbnail($id, 'thumbnail');     // Thumbnail
get_the_post_thumbnail($id, 'medium');        // Medium resolution
get_the_post_thumbnail($id, 'large');         // Large resolution

get_the_post_thumbnail($id, array(100,100) ); // Other resolutions

This is not possible to write such kind of apache rules. I written many apache and Nginx server rule.
The issue with your requirement is your needed new structure.
mysite.com/year/month/post_name
How can we know which month or year need to pass for redirection.

You can go with following approach.
mysite.com/post_name.html to mysite.com/post_name

This is possible with your new site after migration to worpdress without loosing any traffic or broken links.

Your theme developer not added the menu support to your theme. For adding the navigation you dont need to change the code.
If page links not working then just visit the wordpresss admin->setting->permalink page once and then the pagination means page links. that will start working.

you or somebody must be edited the theme code wrongly. You need to reinstall the theme or consult with wordpress developer.
