We create stunning, user-friendly websites that drive growth.
Pages take 10–20 seconds to load. The submission form times out. Readers give up before the article opens. A slow OJS installation isn’t just an inconvenience—it directly affects how authors perceive your journal’s professionalism and how well your articles rank in Google Scholar and other discovery tools. What This Error Means OJS performance problems are...
OJS Submission File Upload Failed: Authors Can’t Submit Manuscripts Authors complete the submission form, try to upload their manuscript, and get an error—or the file appears to upload but never actually attaches. This is one of the most damaging OJS bugs because it happens at the exact moment an author decides to submit to your...
OJS Login Not Working: When You’re Locked Out of Your Own Journal You enter your credentials and the page either reloads silently, throws an error, or logs you out immediately after logging in.

Readers clicking on your published articles see “File not found” or a blank PDF viewer. This is more than an inconvenience—it directly impacts your journal’s reputation, download statistics, citations, and indexing. If Google Scholar or other harvesters encounter these errors, your articles may be flagged or delisted. What This Error Means When PDFs don’t display...
Your OJS journal suddenly shows nothing—just a white screen. No error message, no content, nothing. This “White Screen of Death” is OJS’s way of hiding a critical PHP error from public view. While that’s good for security, it makes troubleshooting incredibly frustrating when you don’t know what went wrong. What This Error Means A white/blank...
If you’re seeing “Database connection failed” or “Error establishing a database connection” in OJS, your journal is completely inaccessible—authors can’t submit, reviewers can’t access manuscripts, and readers can’t view articles. This is one of the most critical OJS errors, and every minute of downtime affects your journal’s credibility and workflow. What This Error Means OJS...
