I'm reaching out for help with a persistent and frustrating issue that I've been experiencing on my WordPress site. Recently, I've encountered a significant problem where I am unable to upload certain images. Each time I try to upload a new image, I receive an error message stating "Upload failed." This problem is causing considerable difficulties, as it affects not only the ability to upload images to the media library but also impacts my capacity to insert images into posts and pages.

The issue started appearing after I performed several updates on my site. Specifically, I updated WordPress to its latest version, along with several plugins and the active theme. While I cannot pinpoint the exact moment this issue began, it seems to coincide with these updates. The error message "File could not be uploaded" is rather vague and does not provide any additional details, making it challenging to determine the exact cause of the problem.

In an effort to resolve the issue, I have undertaken a series of troubleshooting steps. First, I cleared my browser cache and cookies, as sometimes cached data can interfere with the upload process. I also tried accessing the site from different browsers and devices to rule out browser-specific issues, but unfortunately, the problem persisted across all platforms.

Following that, I deactivated all plugins to check if there was any conflict causing the issue. I went through the process of disabling each plugin one by one and tried uploading images again, but the issue continued even when all plugins were deactivated. This suggests that the problem may not be related to any specific plugin.

If anyone has experienced a similar issue or has any insights or additional suggestions, I would greatly appreciate your assistance. Your expertise or advice could be crucial in helping me resolve this ongoing problem. For a quicker response, please feel free to reach out to me on Twitter: ultrabet

To determine if the issue was theme-related, I switched to a default WordPress theme. Despite this change, the issue with image uploads remained unresolved, indicating that the theme is likely not the cause of the problem. Additionally, I edited the file on my server to increase the PHP memory limit, as sometimes insufficient memory can cause problems with file uploads. I also checked the file to ensure that the memory limit was set correctly, but this did not resolve the problem either.

I reviewed the file permissions for the uploads directory to ensure they were set correctly. The permissions were configured to 755 for directories and 644 for files, which is typically adequate. Even with these permissions confirmed, the problem persisted. I also examined the server error logs and access logs for any relevant errors or warnings, but the logs indicated normal server operation, and no entries pointed to issues related to the image upload failures.

Given that my server environment appears to be functioning normally with PHP version 8.0 and that there are no significant errors reported in the server logs, I am finding it difficult to identify the root cause of the issue. Despite the thorough troubleshooting steps I have taken, the problem remains unresolved.
