First, when setting the homepage promotional image and logo position for the website, I tried uploading images in jpg and png formats, but I couldn’t upload any images, and there were no error messages. Then, when adding a journal, I also couldn’t upload files; the upload file box displayed an HTTP error. Below are two images showing my error situation. Does anyone know how to resolve this? Thank you very much!
In the case of HTTP errors, it is best to check your PHP error log. Please see this post: How do I find my PHP error log?, if you’re unsure about how to go about that.
You can post the output from your error log here, and typically that provides more clues as to what the specific issue that is causing this is.
