First, please make sure you post in the appropriate forum category “Celestial Reloaded” as you posted it in the “suggestions” one. Thanks 😛
As for your issue…I think know what it is. Normally I don’t have people make modifications to the core theme files, but this one I think is going to require an update to the theme. Paste this:
.wp-caption {
max-width: 100%; /* Keep wide captions from overflowing their container. */
}
…after this code around line 854 that has this code there:
img.alignnone {
margin: 0 0 1.5em;
}
div.alignnone {
margin-bottom: 1.75em;
}
