Does this also happens when running locally?

I took a look at your posts and everything seems fine. The only "unusual" thing I saw was that none of your posts have either description, tags, or categories. Just to take these out of the equation, can you fill these fields and test again?

[fanyangCS]

I removed all the local posts and it is the same. Maybe it is due to external posts in the _config.yml?

I don’t have a local environment to test.

The mode :bibtex in your error means that your bib file is wrong. I recommend using something like bibtex-tidy to clean and format it a bit. For example, in here you have a \ after a comma that is invalidating your bib file.

Now, about the 2023 blog posts is probably something related to external blog posts, but I am not sure what. This requires further investigation.

[george-gca]

Just found out what is your issue, and yes: it is because of external posts. More specifically, your posts have foreign characters, and as the regex to replace chars in the external posts plugin replace those, the title ends up empty and it gives this error. I will upload a patch for it soon.

I just commited a fix for this issue. Check if cd3f4d6 solves this issue for you. You can either get the latest updates from our repo, or just apply these changes in your own code and test if it works.

[fanyangCS]

Yes, it is fixed. Thanks!
