Where there are Owl_Slider widgets on a page can be better to delete everything and start again but:
The best way:
Activate the Voxco Framework Plugin so that the Owl Slider elements show in the backend editor.
Make notes in a word processor page of all the names of the .jpg images referred to in these elements where abouts they are on the page.
Delete the Owl Slider elements.
Deactivate the Voxco Framework plugin.
Refresh the back end.
View Portfolio Item to check that the bracketed shortcodes are gone.
Add Single Image elements as replacements with Full size and centre alignment.
Check front end.

GTMetrix shows this error message:
So then turn on Load CSS Asynchronously from LiteSpeed Cache > Page Optimization > CSS Settings
This actually creates more problems because when turned on it slows down this blog when using the Scalia theme:
When “Load CSS Asynchronously” is turned off the page is rated a B instead of a C. (This is the case with Voxco theme with Litespeed Cache without Cloudflare, with Cloudflare this combination the rating seems to stay the same. With the Scalia theme without Cloudflare similar negative effect of altering Litespeed in this way but ustilizing Cloudflare as well it goes from a B to an A). Cloudflare itself has no influence except for minification. See here
