The revision of the solar abundances in the early 2000’s has proven to be a thorny issue that is still causing trouble to solar modelers 20 years later. Subsequent re-analyses in 2009, 2011, 2021 and 2022 (Asplund et al. 2009, Caffau et al. 2011, Asplund et al. 2021 and Magg et al. 2022) have provided contradicting result, leading to a lasting debate between “high-metallicity” and “low-metallicity” solar models. In this talk, I will discuss the more general aspects of the so-called “solar modelling problem” and how it cannot be reduced to a simple problem of chemical abundances but rather a more fundamental issue linked with our current modelling capabilities of the solar interior.
