Illegal string offset for 'url' when using WordPress Advanced Custom Fields
There are three ways that an image field can be returned in ACF (array, URL, or ID). It sounds like your field is set to return the URL - which returns as a string.
Therefore, you need to access it like this:
<?php echo $home_page_logo; ?>
instead of this:
<?php echo $home_page_logo['url']; ?>
Alternatively, you can edit the set up for the field in your WordPress admin and configure it to return an image array instead of the URL:
If it's set to the array option, you can access the url
like you are currently doing so, as well as access a range of other data pertinent to the image (such as its width and height, WordPress attachment ID, caption if entered, etc.)

I am converting a Bootstrap template into a WordPress theme.
For custom fields I am using the plugin Advanced Custom Fields. The issue is when I am trying to add an image with the help of Advanced Custom Fields, I get the following error:
Warning: Illegal string offset 'url' in C:\wamp64\www\my-site\wordpress\wp-content\themes\bootstraptowordpress\page-home.php on line 31
However when I am adding text through this plugin it shows no error.
I have no other plugins installed other than ACF.
Here is my code:
$home_page_logo = get_field('home_page_logo'); <div class="front_logo"> <?php if( !empty($home_page_logo)): ?> <img src="<?php echo $home_page_logo['url']; ?>" alt="<?php echo $home_page_logo['alt']; ?>" /> <?php endif; ?> </div>
