was advised<\/a>:<\/p>\n“Don’t worry if you don’t understand the above, simply do as I say below:<\/p>\n
1) Copy the function emphaino_setup() from the functions.php of the parent theme (lines 58 to 135).
\n2) Paste it into the child theme’s function.php.
\n3) Look for the code set_post_thumbnail_size( 150, 150, true ); in the child theme’s functions.php (pasted code) and change the values to whatever you want.
\n4) Save the file and upload as applicable.”<\/p>\n
I tried doing that. <\/p>\n
1) I copied from:<\/p>\n
function emphaino_setup() {<\/p>\n
to…<\/p>\n
add_theme_support( ‘post-formats’, array(
\n‘aside’, ‘audio’, ‘chat’, ‘gallery’, ‘image’, ‘link’, ‘quote’, ‘status’, ‘video’
\n) );<\/p>\n
(I think that’s lines 58-135.)<\/p>\n
—<\/p>\n
2) I pasted that into the functions.php file I created in my child theme directory.<\/p>\n
—<\/p>\n
3) I changed:<\/p>\n
set_post_thumbnail_size( 150, 150, true );<\/p>\n
to…<\/p>\n
set_post_thumbnail_size( 300, 0, false );<\/p>\n
(Because I want to set a width of 300px, and retain the original aspect ratio without cropping.)<\/p>\n
—<\/p>\n
4) I saved the file and uploaded it.<\/p>\n
BUT<\/p>\n
When I refreshed my blog, I found that all of the code I’d entered into the child theme’s functions.php now appeared as text at the top of every page, including my WordPress dashboard. <\/p>\n
