My completed EPUB uploads fine everywhere except Kobo, which keeps throwing the error “OPF file failures – [title] tag is empty.” I’ve already poked around with a few metadata edits in the OPF, so you’ll be working with a file that has seen some light tinkering. I believe I’ve spotted a couple of suspect metadata fields, but the issue persists. What I need from you: • Open the EPUB, review the OPF package and all embedded metadata. • Correct the empty or malformed <title> (and any related) tags without touching the book’s content, images, links, or layout. • Run the repaired file through Kobo’s validator (or an equivalent EPUB-Check) and confirm it passes cleanly. • Return a single Kobo-ready EPUB as soon as possible. No redesigns, no text edits—just a quick, surgical fix so I can hit “Publish” on Kobo without errors.

Hi, You've mentioned the issue with the EPUB file on Kobo due to the empty "<title>" tag error. I have extensive experience in eBook design and have successfully fixed similar metadata issues in the past. For your project, my approach would be to carefully review the OPF package and metadata, identify and correct any empty or malformed "<title>" tags, and ensure the file passes Kobo's validator. I will focus on making precise adjustments without altering the book's content, images, or layout to provide you with a clean and error-free EPUB ready for publishing on Kobo.

Hi, Since the book is already complete, the goal is simply to resolve the Kobo validation issue and get the EPUB ready for publishing. I'll review the metadata, correct any title-related errors, and deliver a clean EPUB without changing the content or layout. What I'll Do: ✔ Review the EPUB package and metadata ✔ Fix title-related validation issues ✔ Check for any additional metadata conflicts ✔ Validate the repaired EPUB before delivery ✔ Return a clean, Kobo-ready EPUB file I've worked with EPUB, KDP, and publishing files and understand how platform-specific validation issues can affect uploads. A few quick questions: • Can you share the EPUB file? • Do you have the Kobo error log available? • Has the EPUB been edited manually or through software such as Calibre, InDesign, or Vellum? I can start immediately and aim for a quick turnaround once I review the file. Best, Ariba

Hi, I can fix this as a focused EPUB metadata repair. I'll inspect the OPF/package metadata, fix the empty or malformed title fields that are triggering Kobo, and leave the book content, images, links, and layout untouched. After the repair I'll return one Kobo-ready EPUB and a short note showing what was changed and how I validated it. Please send the exact title, author name, and any ISBN/identifier metadata you want preserved.
