We have recently upgraded to 1.17.2 and since then have been getting some DB Error #1146. I have pasted an extract from the logs below -

The actual full errors are as follows -

NUMBER ONE

[SELECT A1.* FROM osti_note A1 WHERE A1.ext_id = 'U37370' ORDER BY A1.sort ASC, A1.created ASC]

Table 'fireplac_osti1.osti_note' doesn't exist

I am certainly no expert, but from my little knowledge it looks like the osti_table doesn't exist? Is this something that can be re-created etc? If so, would you be kind enough to provide step by step instructions as I am useless with PHPMyAdmin

Thank you
