UPDATED: June 21st, 2021

Nothing is worse than a website error. Worse and annoying. Today, while I tried to manage a client’s WordPress site, I found a WordPress 5.3 Upload error. “Ok,” I said to myself, “let us find the problem and fix it.”. The first thing I did was to look at the image properties to see its actual size. The image size is about 1900×320 (far lower than the recommendation from the inside of the error).

Hmm… Strange. Usually, I do not have this kind of problem, even if I upload big-size images (which is very rare, but anyway). Maybe we will discuss the image optimization process more and how important this is for your business website.

So, discovering this WordPress image post-processing issue, I researched it and found a quick solution. Furthermore, I found not one but two quick ways to solve this error and get everything to work again.

The first thing I did was look at the WordPress Support forum. The users from there usually find these kinds of errors quickly and come up with solutions. However, this time I was unlucky. Well, the next step was to search on Reddit, and I found a temporary solution for this problem until WordPress solved the issue:

Post-processing of the image failed. If this is a photo or a large image, please scale it down to 2500 pixels and upload it again.

To temporary solve it, you have two options:

1. Add this line to the functions.php of your theme ( or of your child theme ):

add_filter( 'big_image_size_threshold', '__return_false' );

Pay attention to the actions you make, because you can crash the entire website!

2. ( Safer ) Install the “Disable “BIG Image” Threshold” plugin, provided by Jonathan Desrosiers ( Many thanks to you, Jonathan ). You can search the plugin in your Admin Dashboard area -> Plugins, or download it from here: https://wordpress.org/plugins/disable-big-image-threshold/

Looking for a Wordpress transfer from site A to site B, I found back Andrei from Wesites Seller on Google.He was very proactive in his approach, came with hundreds of ideas and lifetime experiences from other migrations. He knows the wordpress, the hosting and php database as the back of his pocket.And we worked out this migration very smooth. Together we solved it, and myself and my business are very pleased with his approach.100% recommendation & kudo's from out of Belgium!

Websites Seller built my resume site. Deliverables were quickly completed, and I was asked for my feedback at each stage of development. All feedback I gave was implemented in a short time.Another great thing is that he comes with smart solutions, regarding stuff which I didn't initially think of (site security, Google site speed optimization and so on). Basically, he was great, staying in touch, keeping me updated and paid attention to what was most important for my site.Overall, I am very happy with the work done. I highly recommend this developer!
