I run a website where I publish manga using WordPress. There is a WordPress plugin MADARA-CORE for uploading manhwa and manga, but the issue is that I cannot upload files larger than 20 MB and sometimes even 60MB.

I don’t really understand what causes the failing, even though the server should be capable of handling even larger files. Sometimes the upload works, but other times it doesn’t. I have tried all versions of PHP but continue to face the same problem.

Currently, I am using the latest PHP version and have increased the PHP settings configurations, including file upload limits and other configurations to facilitate the process, but to no avail. What is the solution?

I tried different and max values for all of these:

php_value upload_max_filesize
php_value post_max_size
php_value memory_limit
php_value max_execution_time
php_value max_input_time

The error message i always get in the console of browser is like that

“Failed to load resource: the server responded with a status of 503
()”

I’ve also tried the same template on my friends host server and I faced nothing like this error. Can you guide me?

This is my server information:

• Server Name: server1428
• Server Location: Europe (France) (which is close to my users)|
• Disk Space: 100 GB
• RAM: 1024 MB
• CPU Cores: 1

So as you can see it’s pretty weird to get error while uploading 60mb using MADARA MANGA PLUGIN! It’s not too large. What could be the issue?

Just another thing to mention I’m using Amazon s3 Bucket to host my files using Amazon API.

UPDATE: looks like the problem was resulting for 3 reasons:

1. Missing AmazonS3 Bucket permission policies.
2. So far Bucket region from my location.
3. Limited hostinger resources – don’t exactly what is the limit but Seems like sometimes Throughput (I/O) is going so high on Resources
   Usage Graph (because of big file size) and also for some reason i can
   only upload a zip that contains 588 files, 95.3 MB.

Here is a list for my upload tests :

1. 242 files, 111 MB -> done
2. 277 files, 94.3 MB -> done
3. 303 files, 89.2 MB -> done
4. 385 files, 137 MB -> done
5. 515 files, 93.5 MB -> done
6. 555 files, 109 MB -> done
7. 576 files, 100 MB -> done
8. 583 files, 112 MB -> done
9. 586 files, 109 MB -> failed
10. 588 files, 95.3 MB -> done
11. 589 files, 105 MB -> failed
12. 590 files, 108 MB -> failed
13. 613 files, 112 MB -> failed
14. 666 files, 130 MB -> failed

even tho it’s still strange for 586 files, 109 MB -> failed and for
588 files, 95.3 MB -> done.
